Question

A force of 10N propels a 350-g toy rocket upwards. The rocket initially starts from rest and the rocket motor burns for 0.1 s. What impulse does the rocket receive from the thrust?
A. 1.0 N•s
B. 3.5 N•s
C. 100 N•s
D. 350 N•s

I only know that D ain't right

Answer 1

Force = 10N

Time = 0.1 s

Impulse = (force) x (time)

Impulse = (10 N) x (0.1 s)

Impulse = 1.0 N-s  (A)

Answer 2

Impulse=force x time
=10N x 0.1s
=1.0Ns
