Acar is traveling with a speed of 23.0 m/s along a straight horizontal road. the wheels have a radius of 0.310 m. if the car speeds up with a linear acceleration of 1.30 m/s2 for 8.60 s, find the angular displacement of each wheel during this period.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
