On-screen applet instructions:
The position of a pickup truck traveling on the x-axis is shown at time t. Use the slider to change t, and observe the relationship between the position curve x(t), velocity curve v(t), and the direction of travel of the truck.
ExamplesA golfer on the moon (where gravitational acceleration equals 1.67 m/sec2) hits a ball whose initial velocity in the vertical direction is 30 meters per second. What is the maximum height the ball reaches?
A meteoroid falling to Earth is discovered when it is at an altitude of 9000 kilometers, traveling at a velocity of 70 kilometers per second. Assuming acceleration due to Earth's gravity is constant, and neglecting air resistance, how fast will the meteoroid be falling when it hits the ground? What will its acceleration be?
