Determine whether the objects in the following problems have kinetic or potential energy (if potential specify either elastic or gravitational) and then calculate it.
KE = 12 mv2 KE = (0.5)(mass)(velocity2)
PEgrav = mgh PEgrav = (mass)(9.8 m/s2)(height)
PEElastic = 12 kx2 PEElastic = (0.5)(spring constant)(how far object is stretched/compressed)
