A cart of mass 5kg is traveling with a velocity of +3m/s.

9.

a. What is the impulse necessary for the cart to come to a stop?

b. What is the impulse necessary for the velocity of the cart to change to +5m/s? (Hint: what is the change in velocity?)

c. What is the impulse necessary for the velocity of the cart to change to -2m/s? (Hint: what is the change in velocity?)
