If not, then what percentage of energy islost" in the collision between the steel ball and the pendulum? (See Equation 6 in part I.)What happens to the remaining energy? Loss of Mechanical EnergyIf we take our reference height for potential energy the line of travel of the ball as it leaves thegun, then the initial potential energy of the ball is zero. Thus, the total mechanical energy of thesystem before the collision is just the kinetic energy of the ball:%3DbeforeAfter the collision, but before swinging has begun, the ball and catcher are at the same height,so the potential energy is still zero. The total energy of the system is just the kinetic energy, butnow it is the kinetic energy of the ball and the catcher, and the speed is different:Eafter=(m+ M)v,? = (m + M)gh = (m + M)gRem(1 – cos e)%3D%3DстUsing conservation of momentum, one can show that Eafteris less than Epefore - often verymuch less. The fractional energy loss in the collision, Q, can be defined asEafterQ =1--EpeforeLab report requirements: Include in your report the following for both methods:
