Deep Dive into High School Physics

Astronauts often undergo special training in which they are subjected to extremely high centripetal accelerations. One device has a radius of 15 m and can accelerate a person at 98 m/s . What is the speed of the astronaut in this device?

In a rotating carnival ride, people rotate in a vertical cylindrical walled room.  During the ride, the floor drops out.  If the room radius is 5.8m, and the rotation frequency is 0.4revolutionspersecond when the floor drops out, what minimum coefficient of static friction keeps the people from slipping down?

A 2kg ball rolls around the edge of a circle with a radius of 0.5m. If it is rolling at a speed of 8ms, what is the centripetal force?

Deimos, a satellite of Mars, has an average radius of 6.3 km. If the gravitational force between Deimos and a 3.0 kg rock at its surface is 2.5 ´10-2 N, what is order of the mass of Deimos?

Because of the conditions that give rise to them, tornadoes do not have the widespread destructive effects of hurricanes. Nevertheless, the winds encountered in some tornadoes are even greater than those at the eyewall of a hurricane. Suppose a small pebble is swept up in a tornado. The pebble is 3.81 m from the center of the tornado and has a tangential speed equal to that of the surrounding wind: 124 m/s. What is the magnitude of the centripetal acceleration of the pebble?

Which of Newton's Laws is demonstrated by a ball rolling to a wall then stopping? 

What is another name for the first law of motion?

A magician pulls a tablecloth out from underneath some dishes without disturbing the

Newton reasoned that the gravitational attraction between Earth and the moon must be _____.

If the mass of Earth increased, with no change in radius, your weight would _____
