Question 3 12. What power does a pump develop to lift 35 L of water per minute irarn a depth of11D m? (1 L at water has a mass of 1.00 kg.) Don't forget to convert mass of water to weight of water to get the force! And make sure your nal time is in seconds! Show all work, including units for full credit. Question 2 3 pts 6. Two people lift a heavy box a distance of 15 m. They use ropes, each of which makes an angle of 15 with the vertical. Each person exerts a force of 225 N. How much work do the ropes do?

Billiards A cue ball, with mass 0.16 kg, rolling at 4.0 m/s, hits a stationary eight ball of similar mass. If the cue ball travels 45 to the left of its original path and the eight ball travels 45 in the opposite direction, as shown in Figure 21, what is the velocity of each ball after the collision? 45 8 8 Figure 21 Show all work or units for full credit
