Question

A. During a tennis match, a player serves the ball at 24.3 m/s, with the center of the ball leaving the racquet horizontally 2.58 m above the court surface. The net is 12.0 maway and 0.900 m high. When the ball reaches the net, (a) what is the distance between the center of the ball and the top of the net?

During a tennis match, a player serves the ball at 24.3 m/s, with the center of the ball leaving the racquet horizontally 2.58 m above the court surface. The net is 12.0 maway and 0.900 m high. When the ball reaches the net, (a) what is the distance between the center of the ball and the top of the net? The position of an electron is given by r=8.21t i -1.48t^2 j+5.09k, with t in seconds and in meters. At t = 3.26 s, what are (a) the x-component, (b) the y-component, (c) the magnitude, and (d) the angle relative to the positive direction of the x axis, of the electron's velocity (give the angle in the range (-180 degree , 180 degree ])?

Explanation / Answer

uring a tennis match, a player serves the ball at 24.3 m/s, with the center of the ball leaving the racquet horizontally 2.58 m above the court surface. The net is12.0 maway and 0.900 m high. When the ball reaches the net, (a) what is the distance between the center of the ball and the top of the net?(a) The equations are :
x = Vo t
y = - (1/2) g t^2 + y
