As denizens of the surface of a spinning planet, we are always in uniform circular motion. imagine you are in nairobi (on the earth's equator) at noon on a monday. answer the following questions only considering the rotation of the earth and not the earth's circular motion around the sun. the radius of the earth is 6371 km. a day is 24 hours.
assuming that you are at at theta = 0 rad at noon on monday and moving in the positive direction, what is your position theta in rad on tuesday at 11: 00 am?

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s
