Question 1:

part a)

Cart 1, having mass m1 = 3.0-kg, moving to the right with a speed of 1.0 m/s has a head-on collision with cart 2 of mass m2 = 3.0-kg that is initially moving to the left with a speed of 1.0 m/s. After the collision, the cart 1 is moving to the left with a speed of 1.0 m/s. What is the final velocity of cart 2?

part b) An object's velocity of +4.10 m/s changes to a velocity of -25.0 m/s in a certain time interval. The mass of the object is 0.450 kg. Determine the impulse applied to the object.
