. Two people are pushing a car of mass 2000 kg.
If they each push with a force of 320 N at an
angle of 15° to each side of the car, calculate the
acceleration of the car, assuming no resistance.
Use the component and trigonometric
methods.

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 .
