Circular Review with Ans - Physics 12
... 57. A satellite orbits the Earth in a circular orbit. Which statement best explains why the satellite does not move closer to the center of the Earth? (1) The gravitational field of the Earth does not reach the satellite's orbit. (2) The Earth's gravity keeps the satellite moving with constant veloc ...

... A driver traveling at 90 km/hr sees the lights of a barrier 40 m ahead. It takes the driver 0.75 seconds to apply the brakes. Once braking begins, the car slows at a maximum rate of 10 m/s2. a. Does the car hit the barrier? [yes, at 14m/s, or overshoots by 10m] b. At the moment the driver notices th ...
