Question

A car starts from rest and accelerates uniformly at 2m/s for 10sec. What is its velocityat the end of 10sec

Answer 1

Hi , there !!

here is your answer :-

u = 0

a = 2m / s²

t = 10s

v = u + at

=> 0 + 2 × 10

=> 20 m/ s


hope it helps !!!!

thanks !!

Answer 2

given :-

u (initial velocity) = 0

v (final velocity) = ?

acceleration = 2m/s²

time = 10 seconds

by 1st equation of motion, we get

==> v = u + at

==> v = 0 + (2 × 10)

==> v = 20m/s

hence, the velocity of the car at the end of 10 seconds will be 20m/s.

HOPE THIS HELPS..!!
