Question

A ball starts from rest and rolls down 16 m down an incline plane in 4s. What is
the acceleration of the ball and what is the velocity of the ball at the bottom of the
inclined plane?

Answer 1

Answer: Acceleration: 2 m/s² Velocity: 8 m/s

Explanation:

given,

u=0m/s

s=16m

t=4sec

1]

s=ut+1/2at²

16 = o × t + 1/2 × a × 4 × 4

16 = 8a

a = 2 m/s²

2]

v=u+at

v=0+2×4

v=8 m/s
