1. The problem statement, all variables and given/known data Relevante for the problem:: - We are taking a course in Newton mechanics Two men, each of mass M = 75.0 kg find themselves standing on an icy lake, a distance d = 5.00 m apart. They each happen to carry a basketball, weighing m = 0.600 kg. In order to move, they get the clever idea of throwing the balls to each other. They throw with speed v = 10.0 m/s (both of them). Assume they throw at the same time. a) With what angle should they throw, in order to hit the other guy? b) How far are the two guys apart, when they receive the balls? c) What is their speeds after they receive the balls? For each question, provide an algebraic expression, as well as a numerical result with appropriate units. 2. Relevant equations Range equ. : D = (v(ball) * sin 2 theta)/ m D = v(person) * t + d 3. The attempt at a solution My idea was to calculate the time when the ball is in the air. For then to see how far the persons have traveled back before receiving the ball again. For then to use the range equ. to find the angle.
