4. A $$144\mathrm{g}$$ baseball moving at $$28.0\mathrm{m}/\mathrm{s}$$ strikes a stationary $$5.0\mathrm{kg}$$ object resting on a frictionless surface. Immediately after the collision the object moves forward at $$1.1\mathrm{m}/\mathrm{s}$$. ( 6 points ) a) $$(2$$ pts) What is the baseball's speed immediately after the collision? b) $$(2$$ pts) Draw a picture showing the directions of the two objects before and after the collision. c) $$(2$$ pts) What is the impulse imparted to the ball?
