Question

The velocity of an object of mass 250 grams increased from 16m/s to 64m/s. find the change in its momentum in MKS units

Answer 1

Answer:

Kinetic energy, K=

2

1

mv

2

If velocity v is doubled so kinetic energy will increase 4 times.

Since displacement and momentum is proportional to velocity so they will increase 2 times but frictional force does not related to velocity.
