1875 N*m an object have from its motion if its mass is 150-kg and it is moving at a speed of 5.0 meters per second.

The correct option is  E.

The power an object has as a consequence of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in case of applying a force. After the work has been finished, energy is transferred to the item, which further moves at a new, constant speed.

The idea of kinetic energy was first proposed in 1849 by William Thompson, who subsequently rose to the position of Lord Kelvin. The amount equal to one-half the object's mass times the square of its velocity is now what we refer to as the kinetic energy of an object.

KE = 1/2*m*v²

KE = 1/2*150kg*(5 m/s)²

KE = 75kg * 25m²/s²

KE = 1875 kg*m²/s²

KE = 1875 N*m

The coin's acceleration is 0.37 m/s²

Acceleration is the rate of change of the velocity of an item with appreciation to time. Accelerations are vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.

Calculation:-

V² = U -2aS

a = U/2S

  = 2/2×2.7

   =  0.37 m/s²

Acceleration is the charge at which velocity modifications with time, in terms of each speed and route.

The sister’s average velocity is 2m/s east. Option B.

Shelly gives her sister a 5-meter lead in the bike race, and the race ends 15 meters east of Shelly's starting point. It takes 5 seconds for my sister to finish the race. Average velocity is calculated by dividing displacement by total time. Average speed is calculated by dividing the total distance traveled by the total time.

calculation:-

Total distance Shelly's sister traveled = 15- 5 = 10

time = 5sec

velocity = displacement / time

= 10/2

= 5 m/s east.

Average acceleration represents the rate at which velocity changes. Divide the change in velocity by the elapsed time to find the average acceleration of something. Velocity is the speed at which the position changes. Average velocity is the rate of change in displacement or position over time. The difference between velocity and relative velocity is that velocity is measured with respect to a reference point relative to another point.

Answer:

Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces.

Explanation:

Fluid friction is the resistance to an object's motion through a liquid or gas. When the motion is occurring in a liquid, it is referred to as viscous resistance. As an example, when an object falls through water, its speed reduces due to fluid friction acting on it.

Answer:

A

Explanation:

B and C are being accelerated , thus not in equilibrium

The correct answer is 13.2 kgm/s

In the question we are given,

Mass = 6 kg

Velocity = 2.2 m/s

According to the Newton's second law of motion it states that the momentum is the product of mass and the velocity of the particle. This Momentum can be said as the measure of motion of the object. It is a vector quantity and it has both magnitude and direction. It can be transferred. As the momentum of the system is conserved when no external force is applied on the system.

In this case,

Momentum (p) = mv

Here,

m = mass

v = velocity

Momentum = 6 * 2.2

Momentum = 13.2 kgm/s

Therefore, the momentum of the 6 kg ball moving with velocity of 2m/s is 13.2 kgm/s.

The velocity of the frame S' is 0.3 m/s.

In dynamics, a reference frame—also known as a frame of reference—is a set of graduated lines that are symbolically attached to a body and used to describe the position of points in relation to it at perticular instant of time.

Given parameters:

The space-time coordinates of two events 1 and 2 in a frame S are:  x₁= 24 m, t₁ = 8 x 10s and x₂ = 48 m, t₂ = 4 x 10s.

Hence, space difference between two events in frame S is: x₂ - x₁ = 48m - 24 m = 24 m.

Time difference between two events in frame S is: t₂ - t₁ = 4 x 10s -  8 x 10s = - 4×10 s.

As in the frame S' in which both the events occur simultaneously:

 x₂ - x₁ = v | t₂ - t₁| { where v = velocity of the frame S'}

⇒ 24 = v ×4×10

⇒ v = 0.3 m/s.

Hence, the velocity of the frame S' is 0.3 m/s.

The overall momentum of the ball is 100kgm/s.

The impact on the induced velocity in the propeller plane is most pronounced close to the blade tips. The original blade element momentum theory does not account for the effect of vortices emitted from the blade tips into the slip stream on the induced velocity field. The induced velocity dispersion along the propeller is greatly influenced by these tip vortices, which produce a number of helical structures in the wake. It uses a tip-loss or correction factor, F, to make up for this shortcoming.

It's harder to stop the airplane taking off.

According to the Newton's third law is for every action, there's an equal and contrary response. The statement means that in every commerce, there's a brace of forces acting on the two interacting objects.

The size of the forces on the first object equals the size of the force on the alternate object.

When we try to stop the object, the same object will ply an contrary force on us.

As we know that force = mass x acceleration.

In these two cases,

The mass of airplane is further than rolling ball and the acceleration by which the airplane takes off is veritably much high than that of a ball.

The force wielded by the airplane will be further than the force applied by the ball.

Thus, it's harder to stop an airplane taking off than the rolling ball because the force applied to stop airplane will be advanced than the ball.
