IB Physics-Topic#2 Mechanics-Qc#18 Projectile motion-Two players are playing table tennis.-May 21
Показать описание
Two players are playing table tennis. Player A hits the ball at a height of 0.24 m above the edge of the table, measured from the top of the table to the bottom of the ball. The initial speed of the ball is 12.0 m s−1 horizontally. Assume that air resistance is negligible.
Show that the time taken for the ball to reach the surface of the table is about 0.2 s.
Sketch, on the axes, a graph showing the variation with time of the vertical component of velocity vv of the ball until it reaches the table surface. Take g to be +10 m s−2.
The net is stretched across the middle of the table. The table has a length of 2.74 m and the net has a height of 15.0 cm.
Show that the ball will go over the net.
