A 3.00 kg object is at rest on a flat, horizontal, frictionless surface. it is struck by a 3.00 g paintball traveling at 80.0 m/s to the left and the paint adheres to the side of the object. After the collision, the object slides a distance of 1.00 m on the horizontal surface and then up a surface made of the same material inclined at 20.0 degrees above the horizontal.

a) what is the speed of the object after the collision with the paintball?

b) what percent of the system's kinetic energy is lost during the collision btw the paintball and the object?

c) what is the maximum height the object will reach as it slide up the ramp?
