The baseball with a speed of 89.0 mph, has 8.12 s in flight

The formulas for the downward vertical launch and the procedures we will use are:

Where:

Information about the problem:

Converting the velocity from mph to m/s, we have:

89 mil/h * (1609,34 m / 1 mil) * (1h / 3600 s) = 39.786 m/s

Applying the maximum time formula for a downward vertical launch, we get:

t max= v₀ / g

t max= 39.786 m/s / 9.8 m/s²

t max = 4.06 s

Applying  the time of flight formula, we get::

t(of) =2 * t max

t(of) =2 * 4.06 s

t(of) = 8.12 s

The initial velocity of the airplane is 258.3 m/s and then final velocity of the airplane is 408.3 m/s.

When gravity first exerts force on an object, its initial velocity defines how quickly the object moves.

The final velocity, on the other hand, is a vector number that gauges a moving body’s speed and direction after it has reached its maximum acceleration.

According to laws of motion,

x = Vi*t = 1/2 at^2

Substituting all the values we have,

10^4 = vi (30) + 0.5(5)(30)

Simplifying it,

Vi = 258.3 m/s

According to motion equations,

Vf = Vi + at

Substituting all the values,

Vf = 258.3 + (30)(5)

Vf = 408.3 m/s

So, we have Initial velocity = 258.3 m/s and final velocity = 408.3 m/s

The force on the car is 1×10^5 N.

The work-energy theorem states that when a force displaces a body, the change in kinetic energy of the body is measured. Conversely, when an opposing force is applied to a body, the kinetic energy of the body decreases by the same amount. It loses kinetic energy. The bodies' loss of kinetic energy is equivalent to the labor they put into resisting the opposing force.

P(B|A) = 0.76

P(A and B ) = 0.2356

P(A or B)   = 0.2356

If A and B are independent, then knowing A doesn't give you any additional information about B and vice versa. Mathematically, this relationship are often represented with the two equations P(A|B) = P(B) and P(B|A)=P(B), as long as A and B are independent. differently to state this is that, no matter B, P(A) doesn't change, or A doesn't depend on B.

To (randomly) throw the primary dart into circle A and the second dart into circle B, you've got to get lucky on two separate occasions.

When throwing the primary dart, your chance of throwing it randomly into circle A is P(A). When throwing the second dart, your chance of throwing it randomly into circle B is P(B). Because the 2 are independent, the multiplication rule, which is usually P(A and B) = P(A|B) * P(B) can be simplified to P(A and B) = P(A) * P(B).

To (randomly) throw darts into either circle, you get two tries, once with A and once with B.

It’s possible that both darts land during a circle. Therefore, the overall addition rule holds, so P(A or B) = P(A) + P(B) - P(A and B).

Given the formulas italicized, you'll plug in your values for P(A) and P(B) to find the other probabilities:

P(A) = 0.31

P(B) = 0.76

P(A|B) = P(B)

P (A|B) = 0.76

P(B|A)=P(B)

P(B|A) = 0.76

P(A and B) = P(A) * P(B)

P(A and B ) = 0.31 ×0.76

                    = 0.2356

P(A or B) = P(A) + P(B) - P(A and B)

The acceleration of the electric car if it takes 1 s for this car to accelerate from 7 m/s to 25 m/s is 18 m/s².

The term "acceleration" refers to the rate and direction at which velocity varies over time. Acceleration is the change in direction or speed of an object or points moving ahead. The frequent change in direction causes motion on a circle to rise even when the speed remains constant.

For all other motions, these effects increase the acceleration. Since acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is a vector quantity as well.

Given:

The initial speed of the electric car, u = 7 m/s,

The final speed of the electric car, v = 25 m/s,

Time taken, t = 1 sec,

Calculate the acceleration as shown below,

Acceleration = Final speed - Initial speed / time

vi1 = 0

according to the kinematic equation,

y1= v1t1 + 1/2 g[tex]t1^{2}[/tex]

then substituting all the values, we have

2h/3 = 1/2(9.8)[tex](t-1)^{2}[/tex]

vf1= 9.8(t - 1)

In the second stage,

t2= 1s

y2= h/3

vi2 = vf1 = 9.8(t - 1)

Acoording to kinematic equation,

y2 = vi2 t2 + 0.5g[tex]t1^{2}[/tex]

substituting the values,

h/3 = 9.8(t - 1) + 4.9

⇒ h= 29.4(t - 1) + 14.7 → 2

From equation 1 and 2, we get,

7.35[tex](t-1)^{2}[/tex] = 29.4(t - 1) + 14.7

if we assume (t-1) = R, we get

⇒R = 4.45

t = R+1 = 5.45s

substituting the value of t in equation 1, we have
