Juggles the clown stands on one end of a teeter-totter at rest on the ground. Bangles the clown jumps off a platform 2.5 m above the ground and lands on the other end of the teeter-totter, launching Juggles into the air. Juggles rises to a height of 3.7 m above the ground, at which point he has the same amount of gravitational potential energy as Bangles had before he jumped, assuming both potential energies are measured using the ground as the reference level. Bangles' mass is 75 kg. What is Juggles' mass?

asked by Cameron
  1. Assuming no loss in the impact(s), then, let
    M=mass of Juggles
    and equate gravitational potential energy (g=acceleration due to gravity)

    75kg*g*2.5=M*3.7*g

    Solve for M.
