Asmall glider is placed against a compressed spring at the bottom of an air track that slopes upward at an angle of 39.0 ∘ above the horizontal. the glider has mass 5.00×10−2 kg. the spring has 600 n/m and negligible mass. when the spring is released, the glider travels a maximum distance of 1.50 m along the air track before sliding back down. before reaching this maximum distance, the glider loses contact with the spring. what is the kinetic energy of the glider at this point?

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 .
