Question

A car and a truck moving with equal kinetic
energies are stopped by applying equal retarding
forces, then :
(a) car will cover more distance before coming
to rest
(b) truck will cover more distance before coming
to rest
(c) both will cover equal distance before coming
to rest
(d) data insufficient

Answer 1

Answer:

option a is correct.

as the car have low mass will move more.

Answer 2

Hence they must be stopped by equal retarding forces. Hence, Kinetic energy and the retarding force cancel out each other and thus displacement is proved to be the same. Hence, both are stopped at equal distances.

OptionC is correct.

Hope it will help you....
