If an object has a momentum of 40 kg·m/s and a mass of 60 kg, what is its velocity?

A. 2400 m/s
B. 1.5 m/s
C. 240 m/s
D. 67 m/s

Answer :

Final answer:

The velocity of an object with a momentum of 40 kgm/s and a mass of 60 kg is 0.67 m/s.

Explanation:

To find the velocity of an object with given momentum and mass, we can use the formula:

Momentum = Mass x Velocity

Given that the object's momentum is 40 kgm/s and its mass is 60 kg, we can rearrange the formula to solve for velocity:

Velocity = Momentum / Mass

Substituting in the given values, we get:

Velocity = 40 kgm/s / 60 kg = 2/3 m/s = 0.67 m/s

So the correct answer is D. 0.67 m/s.
