A punter drops a ball from rest vertically 1 meter down onto his foot. The ball leaves the foot with a speed of 27 m/s at an angle 52° above the horizontal. What is the impulse delivered by the foot? (Use 0.41 kg for the mass of the ball. Assume the punter faces the +x-direction and that the +y-direction is upward. Enter the impulse in kg · m/s and the direction in degrees counterclockwise from the +x-axis.)

A ball of 2 kg travels in the x direction with a velocity of 4 m/s. It collides with a ball of mass 3 kg which is initially at rest. After the collision, the first ball travels at a velocity of 2.5 m/s at an angle of 30 degrees from the x axis. What is the velocity of the second ball? NOTE: what if they stuck together? What kind of collision would that be?

An osprey drops a fish from an unknown height above the water. The osprey was flying at 12 m/s at an angle of 30 degrees below the horizontal at the moment the fish dropped from its grasp as shown in Figure 5. 2.5 seconds later the fish hits the water. The choice of a coordinate system is arbitrary, but for this problem use the coordinate system shown with the y axis going vertically upward and the x axis with the...
