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?

A. 80 m/s
B. 800 m/s
C. 400 m/s
D. 40 m/s SUBMIT​

Answer 1

A. 80 m/s

Step-by-step explanation:

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

`v = (p)/(m) \\`

p is the momentum

m is the mass

From the question we have

`v = (20000)/(250) = (2000)/(25) \\`

We have the final answer as

80 m/s

Hope this helps you
