A test driver at Incredible Motors, Inc., is testing a new model car having a speedometer calibrated to read m/s rather than mi/h. The following series of speedometer readings was obtained during a test run:
| Time (s) | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 |
| Velocity (m/s) | 0 | 0 | 2 | 5 | 10 | 15 | 20 | 22 | 22 |
By measuring the slope of your curve, find the magnitude of the instantaneous acceleration at time t = 9 s.
By measuring the slope of your curve, find the magnitude of the instantaneous acceleration at time t = 13 s.
By measuring the slope of your curve, find the magnitude of the instantaneous acceleration at time t = 15 s.

A test model for a new type of braking system is designed to apply a braking force that decays following an exponential function. For an object moving in the (+) x direction (to the right), the force acts in the opposite direction. When the brakes are applied, the velocity change as a function of time in seconds can be approximated by . v=v(t) = V, e-At where Vo is a constant in [m/sec) and A is a constant in [1/sec)....

5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...
