Question

A car and a motor cycle are moving with the same momentum. When equal retarding forces are applied, the car comes to halt in t1 seconds and the motor cycle in t2 seconds. If the mass of the car is five times more than the mass of the motor cycle, then
A t1 = t2
B t1 = 5t2
C t1 = {1 \over 5}{t_2}
D t1 = 25t2

Answer 1

Answer:

t1=t2

Explanation: Force is directly proportional to the rate of change of momentum. Here momentum and retarding force is same.

So time taken will be same.

Hope it helps!

Answer 2

Answer:

t

1

=t

2

Explanation:

As we know force is directly proportional to the rate of change of momentum.here momentum and retarding force is same.so time taken will be same.

F∝

dt

dp

hence,t

=t
