Question 1

A truck and a car are moving with equal velocity. On applying the brakes both will stop after certain distance, then

(a) truck will cover less distance before rest

(b) car will cover less distance before rest

(c) Both will cover equal distance

(d) of these

Question 2

Correct option (c) Both will cover equal distance

Explanation:

Stopping distance = kinetic energy/retarding force = 1/2mu2/F

= u2/2μg [∵ F = μmg]

So both will cover equal distance.
