Question

calculate the acceleration of a body which starts from rest and travels 87.5m in 5sec???

Answer 1

Hey friend ☺

Here is your answer

initial velocity (u) =0

distance (S) =87.5m

time(t)=5s

WE KNOW THAT

s=ut+1/2(at²)

[SECOND EQUATION OF MOTION ]

87.5=0×5+1/2(a×5²)

87.5=0+1/2(25a)

87.5×2=25a

175=25a

a=175/25

a=7

ACCELERATION OF THE BODY =7m/s²

HOPE THIS HELPS YOU
