A 30kg Ball is shot straight up from the ground with an initial velocity of 75m/s. Using the principle of conservation of energy, find the balls potential energy and kinetic energy when it is 90m above the ground and find the maximum height it achieved.
In a conservative system how do they relate to each other? Since the subject here is work, how are work and energy related
