Change in momentum question:
A 30 kg sled moving at 15m/s accels down a hill to reach a speed of 20m/s. It takes 4.3 secs to reach the bottom of the hill. What is the sled's change in momentum?

Answer 1

The change in momentum is given by\[\Delta p=mv_f-mv_i\]where m is the mass, vi is the initial velocity, and vf is the final velocity.

Answer 2

i got 150 as the final answer is that what you got?

Answer 3

yep
