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?

A small bead with a mass m = 15.0 g slides along the frictionless wire form shown in the figure. The three heights hA = 6.60 m, hB = 5.40 m, and hC = 2.90 m are all measured from the floor. The bead is released from rest at point A. (a) What is the speed of the bead at points B and C? vB = m/s (b) What is the net work done on the bead by the force of gravity as it moves from point B to C?
