Here is a link to Desmos a) A 2.5 kg rock is thrown upward from height = 0 with an initial speed of 22 m/s.  Use conservation of mechanical energy to determine the maximum height that the rock would reach. b) Why is it unlikely the that rock would actually reach that height? c) A 0.75kg rock is thrown downward from a height of 18m with an initial speed of 2.5 m/s.  Use conservation of mechanical energy to determine how fast the rock is moving when it is halfway to the ground.
