A company designed a spring system for loading ice blocks onto a truck. The ice block is placed in a holder H in front of the spring and an electric motor compresses the spring by pushing H to the left. When the spring is released the ice block is accelerated towards a ramp ABC. When the spring is fully decompressed, the ice block loses contact with the spring at A. The mass of the ice block is 55 kg. spring ice block A B 1.2m Assume that the surface of the ramp is frictionless and that the masses of the spring and the holder are negligible compared to the mass of the ice block. a. The block arrives at C with a speed of 0.90 m/s. i. Show that the elastic energy stored in the spring is 670 J. Calculate the speed of the block at A. ii. b. Describe the motion of the block... i. from A to B with reference to Newton's first law. ii. from B to C with reference to Newton's second law. C. Sketch a graph to show how the displacement of the block varies with time from A to C. (You do not have to put numbers on the axes.) d. The spring decompression takes 0.42 s. Determine the average force that the spring exerts on the block. e. One day the ice blocks experience a frictional force because the section of the ramp from A to B is not cleaned properly. The coefficient of dynamic friction between the ice blocks and the ramp AB is 0.030. The length of AB is 2.0 m. Determine whether the ice blocks will be able to reach C.
