THE apparatus shown in the figure below uses a spring to launch a small block along a track. A latch holds the block of mass m in place against the compressed spring (spring constant k) as shown. When the ring is raised the block is launched along the track. The part from B to C has significant friction (coefficient of sliding friction, u). The parts of the track from A to B and from C to E can be considered fric- tionless for this problem and the size of the block can be ignored compared to the distances along the ramp. m WWW d1 d2 D d3 When the block is launched, it gets through the frictional part, rises up the ramp to the point E, a height h above the straight part of the ramp. It then slides back down. On its return, it gets to the point B and stops. The distances are shown on the figure and the angle of the ramp is 0 as shown Qualitative Analysis For the following items, write down the symbol that best completes the sentence: greater than (>), less than (
