Kato and Abel are tennis partners, and are also in the same physics class. They are playing around with the tennis ball machine, which launches tennis balls at an initial speed of 30 m/s. Kato wonders how high and how far the tennis ball can go, and the pair decide to perform several experiments to find out. This simulation shows a projectile launched from the origin. The initial speed of the projectile is 30 m/s. Kato and Abel can use the slider to set the launch angle or enter an angle value by clicking inside the degrees box and then clicking "fire" to set the projectile in motion. They can move the mouse pointer to see readouts of the x- and y-coordinates for any point on the curve. They can click "pause" to stop the simulation at any point and "clear" to remove traces of the projectile paths. Note that in this simulation, air resistance is ignored. y (m) 75 -30 m/s 50 25 Iz (m) 25 50 100 125 Launch Angle 50 degrees Time- .00 fire pause clear Click here to open the simulation in a new window.
