Once you have found the expression for the launch speed in terms of the pendulum swing height, design and carry out an experiment to determine the launch speed. You should take enough data to allow for a starlisticel menalyis no determine the uncertainty in your launch sneed value
Increase in Thermal Energy
Since you know the masses and speeds of the objocts just before and just after the collision, you can calculate the kinetic energies of the system just before and just after the collision. Should kinetic energy be conserved during the collision? Compare the kinetie energy values just before and just after the collision. If it is not conserved, what happens to the lost kinetic energy?
Is overall energy (all forms of energy, not just KE
