Kinetic energy is the energy possessed by a body in motion while potential energy is the energy of a body at rest. Kinetic energy is given by E=1/2MV² where M is the mass of the body while V is the velocity of the body. To get mass we can use the formula M= 2 Ek/V² (Making M the subject) hence mass = (2 ×675)÷35² = 1.102 kg
