A block of mass 35 kg. is sitting on a platform. The platform sitson a spring with k=2000 N/m. The mass is initially at rest.
a) If the platform is depressed a distance of 0.50 meters and heldthere, what is the mechanical energy of the system?
b) The platform is then released and the mass moves upward andeventually flies off the platform. Assume the spring returns to itsrelaxed state (unstretched and uncompressed) after the mass leavesthe platform. What are the kinetic energy, the gravitational pointenergy and the elastic potential energy of the system when the massreaches it's highest point?
c) How high will the block go? (Measure this distance from theheight of the uncompressed platform)

A block of mass 6o kg is sitting on a platform that in turn sits ona spring with a spring constant k=2500 N/m. The block is initiallyat rest. Assume that the gravitational
potential energy and elastic potential energy of the system is zeroat this point.

a. What is the total mechanical energy of the system?

The platform is depressed a distance of 0.3 m and held there.

b. What are the kinetic, gravitational potential, and elasticpotential energies of the system?

c. What is the new mechanical energy of the system?

The platform is released, ejecting the block in the verticaldirection .

d. What are the kinetic, gravitational potential, and elasticpotential energies when the mass reaches its highest point?

e. How high above the platform does the mass go (measure from theoriginal un-depressed position)?

An ingenious brick layer builds a device for shooting bricksupto the top of the wall where he is working. He places a brick onavertical compressed spring with force constant k = 424 N/mandnegligible mass. When the spring is released, the brickispropelled upward. If the brick has mass 1.77 kg and is to reachamaximum height of 2.6 m above its initial position onthecompressed spring, what distance must the bricklayer compressthespring initially? (Note: The brick loses contact with thespringwhen the spring returns to its uncompressed length.)

Give your answer in meters to the second decimal place.

The computer system says the correct answer = 0.46 meters.(Ineed to know the steps needed to obtain this answer, willgiveimmediate and great ratings for clear step by stepoperations.Thanks.)

14.39. A thrill-seeking cat with mass 4.00 kg is attached by a harness to an ideal spring of negligible mass and oscillates vertically in SHM. The amplitude is 0.050 m, and at the highest point of the motion the spring has its natural unstretched length. Calculate the elastic potential energy of the spring (take it to be zero for the unstretched spring), the kinetic energy of the cat, the gravitational potential energy of the system relative to the lowest point of the motion, and the sum of these three energies when the cat is (a) at its highest point; (b) at its lowest point; (c) at its equilibrium position.
