2.2 The Legacy of Galileo, Newton, and Leibniz
By the end of your studying, you should know:
On-screen applet instructions: This applet shows the average velocity over the interval a to a+h, where a can be chosen from the pull down list. A single click in the graph gives an enlarged picture around the point x = a. Another click restores the original size. The value of h can be set on the slider. Click here for further instructions.
ExamplesTwo taxicab drivers decide to race their cabs. The first driver has a 30-second head start, and accelerates at 1 meter per second per second. The second driver accelerates at 2 meters per second per second. How many seconds will it take for the second driver to catch the first?
The distance an object falls in t seconds is given by the formula
The gravitational acceleration on Mars is about 3.7 meters per second per second. If a Martian juggler were to throw a ball straight up at a rate of 25 meters per second, how high would the ball go? How long would it take until it came down again? Use the formulas v(t) = v0 at for the velocity and d(t) = v0t (1/2)at2 for the height of the ball.
