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.

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?

What is the kinetic energy of the ball? What happened to kinetic energy at that position?

QUESTION 05 (a) (i) What is meant by kinetic energy? (ii) What is the relationship between potential and kinetic energy? (b) (i) Explain Hooke's law? What is restoring force? (ii) What is conservation of energy? (c) In Figure, a single frictionless rollercoaster car of mass m = 825 kg tops the first hill with speed v0 = 17.0 m/s at height h = 42.0 m. How much work does the gravitational force do on the car from that point to (i) point A, (ii) point B, and (iii) point C ? If the gravitational potential energy of the car-Earth system is taken to be zero at C, what is its value when the car is at (iv) B and (v) A? (vi) If mass m were doubled, would the change in the gravitational potential energy of the system between points A and B increase, decrease, or remain the same?
