A 3 kg toy car sits at the highest point of a 13 m high hill. The car is gently pushed forward until it begins to roll down the slope. Assuming the car coasts freely, without any friction or air resistance, how much kinetic energy (KE) and potential energy (PE) will it have at each of the indicated points? Complete the diagram by placing the correct label in each bin. Use g = 10 m/s2 for he acceleration due to gravity. The diagram is not drawn to scale.

Potential energy is given by PE = mgh Kinetic energy is given by KE = mv2 2 Figure 7: Trade in joules between potential and kinetic energy Consider the situation in figure 7, the total mechanical energy is 6 J. There is no loss or gain of mechanical energy, only a transformation from kinetic energy to potential energy (and vice versa). The ball, of mass m = 1 kg is released from rest. Answer the following questions: Question #:1 At point A:What is the potential energy of the ball? What is the height of the ball? What is the velocity of the ball at that point? -What is the kinetic energy? Question #:2 At point B, if the potential energy is equal to the kinetic energy (PE = KE = 3 J)What is the height H of the ball? What is the velocity of the ball at that height? Question #:3 At point C, the potential energy is zero. What is the kinetic energy of the ball? What is the velocity of the ball at that point? How would you describe the velocity at this particular point? Explain Question #:4 At point D, the ball is at the same height as in point A, it reaches a maximum height then stops before reversing direction. What is the potential energy? What is the kinetic energy of the ball? What happened to kinetic energy at that position? Question #:5 While the pendulum is oscillating between positions, use the words increase, decrease, or constant to describe the trend of the different forms of energies. Complete table 2 Table 2: Trend of the different forms of energy of a swinging pendulum Question #:6 Using figure 7, identify the corresponding positions A, B and C in figure 8 Discuss the different energies, and speeds of the glider on those points based on your study of the pendulum.Potential energy is given by PE = mgh Kinetic energy is given by KE = mv2 2 Figure 7: Trade in joules between potential and kinetic energy Consider the situation in figure 7, the total mechanical energy is 6 J.

An object of mass m starts from the left with velocity v0 and travels along a track moving right from position 1 to position 5 as shown. The track is completely frictionless, except for a horizontal region of length Δxf, where the coefficient of kinetic friction between the track and the object is μk. The object finally collides with a spring with a spring constant k and comes to rest in position 5 , compressing the formerly relaxed spring by a maximum amount, Δx. Which statements about the mechanical energy of the object-earth-spring system as the object moves from position 1 to position 5 is FALSE? Assume that the center of mass of the block is at the exact same vertical heights as positions 1, 3, and 5 . Note that while the object is moving at positions 1 through 4, the magnitudes of the velocity vectors shown may not be to scale. Note that more than more than one statement might be false (unlike what you will see on the final exam, where you will only be able to select a single response). The potential energy is the same at positions 1, 3 , and 5 . The gravitational potential energy is the same at positions 1, 3, and 5 . The total mechanical energy is the same at positions 1, 2, 3, 4, and 5. The kinetic energy is the same at positions 1 and 3 . The total mechanical energy is the same at positions 4 and 5 . The total mechanical energy is the same at positions 1, 2 , and 3.
