Answer to Question #228634 in Other for Jay

Question

2, A constant force F acting for a certain time t on a body, increases its speed by a factor of 10 as compared to the initial speed. So;

A.     The acceleration of the body has increased by 10

B.     The momentum of the body has increased 10 times

Answer 1

B. The momentum of the body has increased 10 times.

The formula for momentum of body is:

$\rho =mv$

Where

$\rho =momentum$

$m=mass$

$v=velocity$

This means that the momentum of a body is directly proportional to its velocity meaning that, if its speed is increased by a factor of 10, the momentum of the body will increase 10 times.
