You (mass 85 kg) are driving down a road when you approach a large dip in the road. The dip is like a part of a circle with a radius of 30m and as you go through the dip, it is like you are moving in a circle at a constant speed. When you go down into the dip you feel heavier right at the bottom, such that if you were sitting on a scale it would read more than your weight. If you are traveling at 12 m/s when you go into the dip, what would be the reading on the scale

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
