a skier leaves the horizontal end of a ramp with a velocity of 25.0 m/s and lands 70.0 m from the base of the ramp. how high is the end of the ramp from the ground? 10. an astronaut stands on the edge of a lunar crater and throws a half-eaten twinkie horizontally with a velocity of 5.00 m/s. the floor of the crater is 100.0 m below the astronaut. what horizontal distance will the twinkie travel before hitting the floor of the crater? (the acceleration of gravity on the moon is 1/6th that of the earth).
