I had to throw a softball for a lab and record data. How would I solve for Initial Velocity, the angle at which it was thrown, and the Max Height? Data:
Time = 1.2s
Distance = 7.26m
Starting Height(the height at which I released the ball) = 2m

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
