Question

A toy car initially moving with a uniform velocity of $18 m h^{- 1}$ comes to a stop in 2 s. Find the retardation of the car in S.I.units.

Open in App

Solution

Given
initial velocity = 18 kmph=5m/s
Final velocity=0
time =2sec

Applying
v=u+at

0=5+at
-5=2a
So retardation =2.5 $m / s^{2}$

A car is moving with a uniform velocity of 30 m $s^{- 1}$ . It is stopped in 2 s by applying a force of 1500 N through its brakes. Calculate:

(a) the change in momentum of car,
(b) the retardation produced in car and
(c) the mass of the car.
