|
|
150 m/s
|
|
|
35 m/s
|
|
|
6 m/s
|
|
|
5 m/s

Explanation:
Detailed explanation-1: -The momentum of a body of 5 kg mass is ‘10 kg//ms‘.
Detailed explanation-2: -Hence when A body of mass 5 k g undergoes a change in speed from 20 m s-1 to. 20 m s-1 . The momentum of the body decreases by 99 k g m s-1 .
Detailed explanation-3: -The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kg⋅m/s).
