Question

A ball starts from rest and rolls down 16 m down an inclined plane in four seconds .find acceleration and the final velocity ?

Answer 1

Explanation:

u = 0

t = 4s

S = 16m

S = ut + 1/2at²

16m = 0 + 1/2a*16

a = 2m/s²

v = u + at

v = 0 + 2*4

v = 8m/s

Answer 2

Explanation:

your answer is A=2m/s (sq).

Vf=8m/s.
