1D60.10-16 Howitzer and Tunnel (and variations)

Set the cart moving on the track at constant velocity. When the cart passes the photogate, it will launch the ball vertically, causing it to travel parabolically through the air and land back in the cart. Setting the track on an incline will produce the same effect as both the cart and ball are being accelerated by gravity. Accelerating the cart with a weight will make it move faster and cause the ball to fall behind it on the track.

A cart glides smoothly on a slightly inclined track. A metal 'tunnel' rests part-way down the track. A PASCO brand howitzer is fastened to the cart. In the photo shown, the howitzer has just thrown a ball upward, which appears as a small object with trail in the photo. The cart is heading toward the tunnel, with the ball arching above the cart in the same direction.

Note: in the below video, three versions of the same experiment are presented. First the cart moves across the track with constant velocity; then it moves across the track on an incline; and in the third iteration the cart is accelerated by a mass.
