The roller coaster in Figure Q2a starts at the point A from rest. The track is designed in a way such that the passengers should experience no more than 4 times their weights at point B and no less than zero weight at point C. Find the limits on the heights h1 and h2. Neglect friction. Figure Q2a

In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m (Figure 1). The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 5.40 m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest. Figure 1 of 1 m = 0.200 kg Part A What is the coefficient of kinetic friction on the horizontal surface? Submit Request Answer Part B How much work is done on the package by friction as it slides down the circular arc from A to B ? Express your answer in joules. Submit Request Answer

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 roller-coaster car has a mass of 514 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and-down motion (as seen by the riders), with no motion to the left or right. Assume the roller-coaster tracks at points (A) and (B) are parts of vertical circles of radius r1 = 10.0 m and r2 = 15.0 m, respectively. (a) If the vehicle has a speed of 19.1 m/s at point A, what is the force exerted by the track on the car at this point? N (b) What is the maximum speed the vehicle can have at B and still remain on the track? m/s
