Question

A spacecraft has a momentum of 20,000 kg.m/s and a mass of 250 kg. What is the magnitude of of its velocity?
A. 400 m/s
B. 80 m/s
C. 800 m/s
D. 40 m/s

Answer 1

if a body of mass m is moving with velocity v then its momemtum is given by
\[P=mv\]
in ur question \[P=20000\]
and\[m=250\]
now plug those values and solve for V

Answer 2

UM i got 5,000,000

Answer 3

no wait you divide right?

Answer 4

check again
\[P=mv \rightarrow v=P/m\]

Answer 5

\[v=\frac{ 20000 }{ 250 }\]

Answer 6

so the answer is B. 80?

Answer 7

yeah correct

Answer 8

thanks brah (;

Answer 9

np :)
