What is the velocity of an object that has a momentum of 4,000 kg·m/s and a mass of 115 kg?

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

Answer :

Final answer:

The velocity of an object with a momentum of 4,000 kg-m/s and a mass of 115 kg is calculated by dividing the momentum by the mass, resulting in a velocity of 34.78 m/s, which is Answer A.

Explanation:

To find the velocity of an object given its momentum and mass, you can use the formula: Momentum = mass × velocity. By rearranging this formula, you can solve for velocity: velocity = Momentum / mass.

So, if an object has a momentum of 4,000 kg-m/s and a mass of 115 kg, the velocity can be calculated by dividing the momentum by the mass:

velocity = 4,000 kg-m/s ÷ 115 kg

velocity = 34.78 m/s

Therefore, the velocity of the object is 34.78 m/s, which corresponds to Answer A.
