The international space station has a mass of 1.8 × 105 kg. a 70.0-kg astronaut inside the station pushes off one wall of the station so she accelerates at 1.50 m/s2. what is the magnitude of the acceleration of the space station as the astronaut is pushing off the wall? give your answer relative to an observer who is space walking and therefore does not accelerate with the space station due to the push.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?
