Assume that the maximum horizontal distance you can throw a baseball (m = 0.145 kg) at an angle of α0 = 45∘ above the horizontal is 25 m. Part A) What is the kinetic energy of the baseball just after it leaves your hand? Ignore air resistance and the small distance the ball is above the ground when it leaves your hand. Take the zero of potential energy to be at the ground. Part B) At the ball's maximum height,...

Observer A stands at the top of the cliff and throws a ball straight upwards with a speed of 30 m/s. Observer B is flying in a helicopter that is going straight upward with a speed of 30 m/s. At the moment that observer B passes observer A, B releases a ball. B simply lets go of the ball and does not throw it. (Assume that air resistance has a negligible effect on the balls.) Be sure to include direction...
