The kinetic energy of an object is given by: Kinetic energy = 1/2 * mass * velocity If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0
You would add 5 and 17 and that would equal 22 Now it would be 22=J-14 Then add 14 on both sides so it cancels out 22 plus 14 is 36 So J would equal 36
