Question

A spacecraft has a momentum of 20,000 kg-m/s, and a mass of 250 kg. What is the magnitude of its velocity?

Answer 1

Answer:

A. 80 m/s

Explanation:

The velocity of the spacecraft can be found by using the formula

$v = \frac{p}{m}$

p is the momentum

m is the mass

From the question we have

$v = \frac{20000}{250} = \frac{2000}{25}$

We have the final answer as

80 m/s

Hope this helps you
