The acceleration, in m/s² , that riders experience is 50.3 m/s²
What is the acceleration, in m/s² , that riders experience?Since the riders move in a circle, they undergo circular motion and will have a centripetal acceleration.
So, the centripetal acceleration, is given by a = v²/r where
v = speed of rider andr = radius of circleGiven that a rider in one swing is moving at 34 m/s with respect to the ground in a 46- m -diameter circle. We have that
v = speed of rider = 34 m/s and r = radius of circle = 46/2 = 23 mSo, substituting the values of the variables into the equation for the acceleration, we have
a = v²/r
a = (34 m/s)²/23 m
a = 1156 m²/s²/23 m
a = 50.26 m/s²
a ≅ 50.3 m/s²
So, the acceleration, in m/s² , that riders experience is 50.3 m/s²

A ball accelerates uniformly at −2.00 m/s2.
If the ball was initially moving at 0.20 m/s and the ball travels for 7.00 s, then what was its final velocity?
The final velocity of a ball that accelerates uniformly at -2.00m/s² and moved at 0.20 m/s for 7.00 s is 14.2m/s.
How to calculate final velocity?The final velocity of a moving body can be calculated using the following formula:
a = v - u/t
Where;
a = acceleration (m/s²)v = final velocity (m/s)u = initial velocity (m/s)t = time (s)According to this question, a ball accelerates uniformly at −2.00 m/s². If the ball was initially moving at 0.20 m/s and the ball travels for 7.00 s, the final velocity is as follows:
-2 = (v - 0.2)/7
-14 = v - 0.2
v = 14.2m/s
Therefore, final velocity of a ball that accelerates uniformly at -2.00m/s² and moved at 0.20 m/s for 7.00 s is 14.2m/s.

an object is dropped from a 32m tall building. How fast will it be going when it strikes the ground?
The total velocity of the object which is thrown vertically from a building of 32m tall in the presence of the air will be 25.04 m/sec.
How fast will it be going when it strikes the ground if an object is dropped from a 32m tall building. ?If there is no air resistance means that the air resistance is zero, then the formula of the velocity is given by;
velocity = sqrt(2xgravityxheight)
where v represents velocity, h represents distance , g represents gravitational constant, and m represents meters, so here in this case by putting the values we can get this which is below;
velocity = square(2*(9.8m/sec2)*32m)
velocity = square(627.2 m2/sec2)
velocity = 25.04 m/sec.

on a day the wind is blowing towards the south at 7 m/s, a runner jogs west at 7 m/s. what is the velocity (speed and direction) of the air relative to the runner?
Velocity is the rate of change of position of an object. The velocity of the air relative to the runner is 5√2 m/sec and it is in the southwest direction.
What is Velocity?Velocity is the directional speed of a moving object as an indicator of its rate of change in location as perceived from a certain frame of reference and measured by a specific time standard.
Given that on a day the wind is blowing towards the south at 7 m/s, a runner jogs west at 7 m/s. Therefore, the velocity of the air relative to the runner can be written as,
Relative velocity = √[(Velocity of the jogger)² + (Velocity of the air)²]
= √[(5)² + (5)²]
= √(25 + 25)
= √50
= 5√2 m/sec
The direction of the relative velocity is,
The angle of relative Velocity = Tan(θ)
Tan(θ) = Vertical velocity / Horizontal velocity
Tan(θ) = 5/5
Tan(θ) = 1
θ = tan⁻¹(1)
θ = 45°
Since this angle is formed between the two velocities, therefore, the direction of the velocity is southwest.
Hence, the velocity of the air relative to the runner is 5√2 m/sec and it is in the southwest direction.

I use a rope 2.00 m long to swing a 10.0-kg weight around my head. The tension in the rope is 20.0 N. In half a revolution how much work is done by the rope on the weight?
According to the given assertion, the work done during half revolution also will be equal to zero.
Why is effort done inside a circle equal to zero?When a body is spun in a circle, the work done equals zero because displacement in circular motion is always perpendicular to the applied force. Also, when a body moves in a circular direction, the centripetal force works along the radius of the circle and is perpendicular to the body's motion.
What is the work-done calculation formula?The following equation can be used to determine work: Work equals Force x Distance. The joule (J) or Newton meter (N m) is the SI unit for labor. One joule is the amount of work done when one Newton of force pushes an object one meter.
Briefing:The work done by the centripetal force is always zero since force and instantaneous displacement are always perpendicular. As a result, effort done in half revolution is likewise equal to zero.
