Draw a pictorial representation for the following problem. Do not solve the problem. What acceleration does a rocket need to reach a speed of 200 m/s at a height of 1.0 km?
Draw a pictorial representation for the following problem. Do not solve the problem. The light turns green, and a bicyclist starts forward with an acceleration of 1.5 m/s2. How far must she travel to reach a speed of 7.5 m/s.
Figure EX1.18 shows the motion diagram of a drag racer. The camera took one frame every 2 s.
Measure the x-value of the racer at each dot. List your data
in a table similar to Table 1.1, showing each position and the
time at which it occurred.
Make a position-versus-time graph for the drag racer.
Because you have data only at certain instants, your graph
should consist of dots that are not connected together.
Your roommate drops a tennis ball from a third-story balcony. It hits the sidewalk and bounces as high as the second story. Draw a complete motion diagram of the tennis ball from the time it is released until it reaches the maximum height on its bounce. Be sure to determine and show the acceleration at the lowest point.
A roof tile falls straight down from a two-story building. It lands in a swimming pool and settles gently to the bottom. Draw a complete motion diagram of the tile.
You use a long rubber band to launch a paper wad straight up. Draw a complete motion diagram of the paper wad from the moment you release the stretched rubber band until the paper wad reaches its highest point.
