Question

A ball of mass 100 grams is moving with a velocity V is equal to (2i+2j+2k)m/s. Then the momentum of the ball is ​

Answer 1

Answer:

Massofball=100g

Velocityofball=10m/s

Ballstopbyboyin0.2sec.

Force=mass×acceleration

 but acceleration=initial velocity - final velocity/time

but initial velocity=10m/s and final velocity=0m/s

Time=0.2second

 Acceleration=0.210−0=50

Force=m×a=100×50=500Newton
