PLEASE help me. When performing a serve, a tennis player throws the ball horizontally from a height of 2.40 m. The height of the net is 0.90 m and it is 15.0 m from the player. See the figure on the side. a) Determine the minimum throwing speed necessary for the ball to pass without touching the net. The ball is launched with the minimum speed vmin (obtained in the item above). Determine: b) the time that the ball remains in the air; c) the distance in relation to the player where the ball will touch the ground; d) the speed ⃗v with which the ball passes over the net.
