Aphoto frame weighing 4.16 newtons is hanging by a wire making an angle with the horizontal. the tension experienced by both wires is 3 newtons. what angle is made by both wires with the horizontal?

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 .
