4. (20 pts) A small 303 block is released from rest at the top of a curved frictionless ramp of height 180cm. The block slides down the ramp, then 5m across a rough horizontal surface of coefficient of friction 0.1. The block then moves up a second frictionless curved ramp. What is the highest height reached by the block on this second ramp? 5. (20 points) Two birds, both ying parallel to the ground, collide in mid-air. The first bird was ying due north at a speed of 15 m/s right before the collision. The second bird, of mass three times the mass of the first bird, was flying at a speed of 6 m/s at 30 degrees south of west. If the first bird is brought to a dead stop by the collision, what is the velocity of the second, larger bird immediately after the collision, expressed in component form
