The ball rolls off the inclined chute in 3 seconds. is the movement of the ball uniform? What is the average speed of movement along the chute if its length is 45cm?

Given:

t = 3 seconds – the time it takes for the ball to roll down the inclined chute;

L = 45 centimeters = 0.45 meters – the length of the inclined gutter.

It is required to determine whether the movement of the ball is uniform, as well as the average speed of movement of the ball along the groove Vav.

The ball rolls down the chute due to gravity. This force gives the ball an acceleration equal to the acceleration of gravity (g = 9.8 m / s ^ 2). Since the ball has acceleration, its movement is not uniform.

Vav = L / t = 0.45 / 3 = 0.15 m / s.

Answer: the movement of the ball is not uniform, the average speed of the ball is 0.15 m / s.
