Question

A ball of 200 g mass is thrown with initial velocity of 0.01km/s.What is its momentum at that time?

Answer 1

Answer:

2 gkm/sec

Explanation:

momentum is mass into velocity

Answer 2

Answer:

2 kg.m/s^2

Explanation:

Momentum = Mass x velocity

p = mv

Convert g to Kg

1 kg = 1000g

1g = 1/1000 kg

200 g = 200/1000 = 0.2 kg

Convert km to m

1 km = 1000m

0.01 km = 0.01 x 1000g = 10 m

p =
