An object accelerates from rest to a velocity of 22 m/s over 35 m what was it’s acceleration

6.91 m/s/s

Explanation:

First Solve for t (displacement)

t=2s/(v+u)  2x35m= 70m/22 m/s= 3.18 seconds

a=acceleration

v= final velocity

u= initial velocity

s= displacement

t= time

Then acceleration:  a=v−u/t

a= 22m/s-0m/s = 22m/s divide by  3.18s = 6.918m/s/s
