When an object, in your example, a ball, rolls (with rolling friction) bounces off of another surface, the force from the barrier is transferred into the ball causing it to roll back. (Newton’s third law)

Hope that makes since

If you throw a tennis ball in the air,what type of motion does it have?
Alenkasestr [34]

-- Accelerated motion. Its speed changes constantly. If it's not tossed STRAIGHT up, its direction also changes constantly. Even if it IS tossed straight up, its direction changes when it gets to the top and starts falling.

-- Projectile motion. There is vertical force on the object because of gravity, but no horizontal force.

A boy whirls a ball on a string in a horizontal circle of radius 1 m. How many revolutions per minute must the ball make if its
spayn [35]

Answer:

Nearest, the revolutions per minute will be 29.

Explanation:

Given that,

Radius of circle = 1 m

Acceleration a =g

We know that,

Angular frequency is defined as,

\omega=2\pi n

Where, n = number of revolutions in one second

We need to calculate the revolutions in one second

Using formula of centripetal acceleration

a=\omega^2r

Put the value of a and ω

g=(2\pi n)^2r

n=\sqrt{\dfrac{g}{r}}\times\dfrac{1}{2\pi}

Put the value into the formula

n=\sqrt{\dfrac{9.8}{1}}\times\dfrac{1}{2\pi}

n=0.49

We need to calculate the revolutions per minute

Using value for the revolutions per minute

n=0.49\times60

n=29.4

Hence, Nearest, the revolutions per minute will be 29.
