Solve for the following problem. Use the formula K=1/2 mv2for Kinetic energy and/or P=mgh for Potential energy. (Show your solution) 1. A rock has kinetic energy of 110 j and is traveling at a velocity of 3 m/s. What is the mass of the object?
2. What is the weight of an object that has gravitational potential energy of 3200 N-m if it is dropped from a height of 12m?
with solution pleaseee JEBALLLLL
