wo men on a plank that is sitting on frictionless ice both have a I'D-kg medicine ball. Man A on the left is m1 = ED kg and man 3 on the right is m2 = 100 kg and the plank is mp = 50 kg. The plank is 10 m long and it has a bucket in the middle of it. Let the position of man A be all = U. The plank is initially at rest and there are no unbalanced external forces on it orthe svstem. Man B throws the ball towards the bucket with a horizontal velocity of 3 mi's. Before it hits the bucket. what is the speed of the plank. the other ball and the men relative to the ice? and after that Man A throws the ball into the bucket. After the ball falls into the bucket at what position is man A relative to the frame of reference of the ice? and finallehat is the relative horizontal speed ofthe two balls while the thrown ball approaches the ball in the bucket
