Page number 1. A 3600 kg speed boat is coming toward the docks and slows with an acceleration of 1.49 m/s2. If ittakes 15.0 s to come to rest, how much work does the water resistance do on the boat? 2. The suspension springs on a 635 kg dune buggy have a spring coefficient of 1.05 106 N/m. How muchenergy is stored in the spring after the buggy drops from a small ledge with the spring deforming by0.122 m? 3. A 1400 kg space capsule is originally orbiting the Earth at a velocity of 7.66 km/s. If it fires its 4.5 kNretrorockets to slow down the capsule to 3.45 km/s, calculate how far the capsule moves during theprocess using the work-energy theorem. 4. A 61.0 kg rock climber is ascending the Half Dome at Yosemite Nation Park. a) If she has used 494 kJof energy, how far up has she climbed? b) How much energy does she need to reach the top at 1444 m? Write down the key words or phrases for the following problems (5 & 6). Do not fully solve the problem.Do not solve the equation for the missing variable. 5. A golf club strikes a 0.045-kg golf ball in order to launch it from the tee. For simplicity, assume thatthe average net force applied to the ball acts parallel to the ball's motion, has a magnitude of 6800 N,and is in contact with the ball for a distance of 0.010 m. With what speed does the ball leave the club? 6. A pole-vaulter just clears the bar at 5.80 m and falls back to the ground. The change in the vaulter'spotential energy during the fall is 3.70 103 J. What is his weight
