Question

What is the velocity of an object that has a momentum of 4,000 kg-m/s and a mass of 115 kg? Round to the nearest hundredth.

A. 35.67 m/s
B. 34.78 m/s
C. 37.43 m/s
D. 36.5 m/s

Answer 1

Answer:

B. 34.78 m/s

Explanation:

Momentum of a body or an object is given as the product of its velocity and its mass.

Therefore;

Momentum= velocity x mass

But; velocity = ? mass =115 kg , momentum = 4,000 kgm/s

Thus; velocity= momentum/mass

                      = 4,000/115

                       = 34.78 m/s
