A lorry and a car moving with the same `KE` are brought to rest by applying the same retarding force. Then

Options

A. Lorry will come to rest in a shorter distance
B. Car will come to rest in a shorter distance
C. Both come to rest in a same distance
D. None of the above

Answer

C

Explanation

Stopping distance `= ("kinetic energy")/("retarding force") rArr s = (1)/(2)(m u^(2))/(F)`
If lorry and car both possess same kinetic energy and retarding force is also equal then both come to rest in the same distance.
