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:

p = mv

p = (200/1000)(10)

p = 2 kg(m/s)

Answer 2

Answer: 2 kg m/s

Explanation:

Momentum(p) = mass(m) x velocity(v)

Mass = 200g or 0.2kg

Velocity = 0.01km/s or 0.01*1000m/s

P = 0.2 * 10 = 2kg m /s
