Use the following information to answer the next question. The diagram shows a pendulum bob that has been pulled to the right by an angle e. Diagram is not to scale. 3. The pendulum has a length of 1.20 m and a bob of mass 2.50 kg. The pendulum bob is pulled sideways until it is 30.8 cm above its rest position. What will be its kinetic energy when it passes through the lowest point of its motion? (5 marks) Use the following information to answer the next question. The diagram shows a motorcyclist attempting to jump over a stack of 5 city buses. He takes off from the ramp on the left and lands on the ramp on the opposite side of the buses. The flight path is represented by the broken line. [Stunt done on a closed course by a professional driver.] Diagram is not to scale. 2. A 175 kg motorcyclist and motorcycle leave the 2.50 m high ramp on the left with a speed of 90.0 km/h and passes over the buses with 1.20 m to spare at a speed of 58.0 km/h. What is the height of each of the five buses? (5 marks) SHORT ANSWER: Show all of your work. Be sure to provide proper units, direction, and significant digits. Be sure to solve these questions using the concepts and skills of the current unit - work, energy, and power. 1. A skateboarder who has a mass of 68.6 kg, comes down a ramp and coasts across a level roadway. At the bottom of the ramp, the skateboarder has a speed of 4.92 m/s. After coasting for a distance of 35.0 m, friction has slowed him down to a speed of 1.12 m/s. What is the work done by friction on the skateboarder? (5 marks)
