A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. The cabinet starts from rest. What is the final kinetic energy of the cabinet at the end of the ramp, in Joules? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
speed will be v=3.76ms A water skier is being pulled by a tow rope attached to a boat. As the driver pushes the throttle forward, the skier accelerates. A 72kg water skier has an initial speed of 6.0m/s. 5.0 seconds later, the speed increases to 11.2m/s. What is the net work done on the water skier? If we assume the efficiency in converting kinetic energy from the boat to the water skier is only 20%, what is the power of the boat? What is the amount of work done by the resistive force during the 5-second period? Answer: W =m(v -v)- 3219.84J × 3.2×10°J net 3219.84J The power of the boat will be P=- = 3.2x10 W 0.2x5s =-3.2×10'W×0.8×5s =-1.3×10ʻJ resistive W. 3
