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)?
