A moving truck crashes into a stationary car. The truck's mass is ten times that of the car. How does the magnitude of the force exerted by the truck on the car compared with the exerted by the car on the truck

A

The force the truck exerts on the car is ten times bigger.

B

the force that the truck exerts on the car is ten times smaller

C

The ratio depends on the speed of the truck

D

They are the same

Text Solution

Verified by Experts

The correct Answer is:
D
Impulse imparted on car `F_1t`- change in momentum `Delta p_c`
Impulse imparted on truck `F_2t`= change in momentum =`Delta p_R`
`because =Delta P_c= Delta p_T`
`therefore F_1=F_2`
