Question

A car starts from rest and travels with a uniform acceleration. The car travels 100m in 5s. What will be its final velocity?​

Answer 1

given

u=0

s=100m

t=5s

so, v=?

Explanation:

using 2nd equation of motion =s=ut+1/2at square

=100m=0*5+1/2a*25

=100=0+1/2a*25

=1/2a =100/25

1/2a=4

a=2m/s

so v= u+at

v=0+2*5

v=10m
