Q # 01: Consider a ball of 100g dropped with zero velocity from the height of 2m.
Estimate its total energy in eV units.
Using the energy conservation, find out the velocity as a function of position of the ball. Sketch its phase trajectory.
Calculate the time it takes to reach the ground.
Let’s assume that it is bounced back with no loss in its total energy.Will it reachthe same height? Make an analytical argument.
What if the collision with the ground is not elastic and it loses some of its energy (which energy?).The ball will eventually come to rest after bouncing few times. Sketch the phase trajectory for the whole duration.
