An imperial soldier on the planet Hoth stands on top of a 22.5 meter tall AT-AT Walker and throws a blaster straight down with an initial velocity of 9 m/s. Assuming no air resistance, what is the magnitude of the impact velocity (in m/s) as it crashes into the snow? *The planet Hoth has a slightly higher force of gravity than Earth. Objects there accelerate at a rate of 11 m/s²

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

An athlete is holding 24 lb of weights at a height of 6 inches above the stack as shown. to lower the weights, she applies a constant force of 5 lb to the handle. determine the velocity of the weights immediately before they hit the stack.

Which of these activities increases the amount of carbon in the atmosphere?
