find the kinetic energy of mass is equal to 20 kg height is equal to 4 m and G is equal to 10 metre per second

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 .

Find the mass by adding the numbers from the three sliders

Wind and moving water provide energy. question 1 options: chemical mechanical thermal none of the above
