The problem involves a basketball dropped from a height of 1.4 m that rises to 66% of its original height after the first bounce. The focus is on calculating the energy dissipated during this bounce.
The discussion is ongoing, with participants exploring the relationship between potential and kinetic energy. Some guidance has been provided regarding the potential energy after the first bounce, but there is no explicit consensus on the method to calculate the energy dissipated.
Participants express uncertainty about the need for additional information, such as speed, and the implications of the problem's wording regarding the initial conditions of the basketball's drop.
how do i find how much energy it starts with, i thought that would be the potential energy? would i need to find energy by adding potential and kinetic, cause if so, i don't have a speedolivermsun said:
wouldn't i still need the final energy to calculate the kinetic energy of the first bounce? after the bounce is 66% of the original height so 0.924molivermsun said:

how?olivermsun said:
do i just subtract potential energies from the start and the max of second bounceemily081715 said:
the answer is 3.3 thanks for walking me throughemily081715 said:
