Question

A body is start from rest by the action of a constant force 22 N . If the force acting for 4s and mass of body is 4kg. Then find the distance travel in 10 s from starting.

Answer 1

u=0
f=22N
t=4s
m=4kg
S10=?

sn=u+a/2(2n-1)
f=ma
22=4a
a=22/4
a=5.5ms²
s10=0+5.5/2(2*10-1)
S10=5.5/2(20-1)
S10=5.5/2(19)
S10=2.75(19)
S10=52.25
S10=52.25metre
