Answer to Question #146924 in Physics for Atef

Question

A force of 20N acts on a rocket for 350secs, causing the rockets velocity to increase. By how much does the rocket’s momentum increase?

Answer 1

We can find the magnitude of the rocket’s momentum increase from the impulse-momentum change equation:

$$\Delta p =F\Delta t=20\ N\cdot 350\ s=7000\ N\cdot s.$$

Answer:

$\Delta p =7000\ N\cdot s.$
