1. A 1.25 kg block of wood sits at the edge of a table 0.752 m above the floor. A 10.5 g bullet moving horizontally with a speed of 725 m/s hits the block and embeds itself within the block. How far from the edge of the table does the block and bullet land? 2. A 12,600 kg railroad car travels alone on a horizontal track with a constant speed of 18.0 m/s. A 5,350 kg load, initially at rest, is dropped onto the moving railroad car. What will be the car's new speed? Round your answer to one decimal place and include units. 3. A 150 g baseball is thrown toward home plate with a speed of 40.0 m/s. The batter hits the ball directly back at the pitcher with a speed of 50.0 m/s. What is the change in momentum of the ball? Round your answer to the nearest tenth and include units. 4. 12.5 kg toy car, initially at rest is subject to a variable force as shown in the graph below. What is the final velocity of the car?
