An 8.0-g bullet is shot into a 4.0-kg block, at rest on a frictionless horizontal surface (see thefigure). the bullet remains lodged in the block. the block moves into an ideal massless spring andcompresses it by 8.7 cm. the spring constant of the spring is 2400 nm. the initial velocity of the
bullet is closest to

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 .
