A rubber ball dropped from a height of 2 bounces back to a height of 1. Draw the ball's position and velocity graphs, stacked vertically, from the instant you release it until it returns to its maximum bounce height. Pay close attention to the time the ball is in contact with the ground; this is a short interval of time, but it's not zero. Assume time the ball is in contact with the ground is 0.05 . Take that y-axis is directed upwards.
A distant galaxy is simultaneously rotating and receding from the earth. As drawing shows, the galactic center is receding from the earth at a relative speed of uG = 1.8 x 10^6 m/s.
A cylinder of gas at room temperature (20°C) has a pressure p1. To what temperature in degrees Celsius would the temperature have to be increased for pressure to be 2.7p1.
Speedy Sue, driving at 33.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 175 m ahead traveling with velocity 5.10 m/s. Sue applies her brakes but could accelerate only at -2.00 m/s2 because the road is wet. Will there be a co..
