Question

A bobsled has a momentum of 3000 kg•m/s to the east. After the rider gives it a push, its momentum increases to 5500 kg•m/s to the east. What impulse is applied to the bobsled?

Answer 1

Impulse, denoted as J, is defined by the change in momentum. Since we have our initial and our final, we can solve for the change in momentum.

$J = p_{f} - p_{0} = 5500 - 3000 = 2500 J = 2500 kg*m/s$

Answer 2

Answer:

2500 kg m/s EAST
