Question

What is the mass of a baseball thrown at 20 m/s resulting in a momentum of 4 kgm/s?

Answer 1

Explanation:

• Mass of baseball (M)= ?
• Velocity of baseball (v) = 20 m/s
• Momentum of baseball (p) = 4 kg m/s

Momentum = Mass × Velocity

p = M × v

M = p / v

M = 4 / 20

M = 0.5 kg = 500 gram
