The graph in the figure shows the velocity of a motorcycle police officer plotted as a function of time.
a. Find the instantaneous acceleration at t = 3, t = 7, and t = 11.
b. How far does the officer go in the first 5 s, first 9 s, and first 13 s?
Figure (a) shows a red car and a green car that move toward each other. Figure (b) is a graph of their motion, showing the positions xg0 = 275 m and xr0 = -35 m at time t = 0. The green car has a constant speed of 16 m/s and the red car begins from rest. What is the acceleration magnitude of the red car?
For the following graphs of position versus time (in one dimension), please determine the acceleration.
Options: {positive acceleration/ negative acceleration/ no acceleration/ First negative then positive}
