What was the initial speed, in m/s, of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0° above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45° when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus 38° will give a longer range than 45° in the shot put.) v0 =arrow_forward
- A regulation volleyball court measures L = 18.0 meters in length and d = 2.43 meters in height. A volleyball player hits the ball from a height of h = 1.50 m just over the backline, and the initial velocity of the ball creates an angle of q = 30° with the ground.

By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short.)arrow_forwardA tennis player serves the ball with an initial speed of 23.6 m/s, from a height of 2.37 m above the court. If the net is at a distance of 12 m and has a height of 0.90 m, determine what is indicated in each section: a) The angle that the throw must have so that the ball can pass over the net. b) The time it takes for the ball to hit the ground, assuming the person on the other side of the net fails to return it. c) If the other person has a height of 1.70 m, and his throw is made at 2.20 m, indicate in what position he must be in order to return the ball.arrow_forward
