A ball is projected vertically from a moving cart. Select parameters such that the ball will land in the cart. Velocity vectors are shown on the cart and the ball.

Global Crossing (TPT 9-04): Two cars X and Y approach an intersection of two perpendicular roads as shown. The velocities of the cars are vx and vy. At the moment when car X reaches the ..

Start the applet. Blue moves in a circle at constant speed. At t=0, Blue releases a green ball. Note the path taken by the ball.
1. At t=0, suppose Blue throws the ball directly opposite his ..

A projectile is launched at an angle from a cliff. A target moves at 0, constant, or uniformly changing velocity. Hit the target with the projectile. Velocity vectors are shown on the projectile.

Change the pursuer's x- and y-velocity components to intercept the target. When you are successful, you can make the circle fit inside the square by stepping the animation. Note that there is more than one ..

Vectors A, B, and C are shown in a tip-to-tail arrangement with vector A starting from the origin. Change the components of vector C in order that the sum of the three vectors is 0. Click ..
