An astronaut is inside a centrifuge that has a radius of 10 m. The astronaut is experiencing 10g, meaning that the centripetal acceleration is ac=98ms2ac=98ms2. The angular velocity of the astronaut is

A flywheel is rotating at 36.5 rev/s.What is the total angle, in radians, through which a point on the flywheel rotates in 29.7 s?

a satellite in a circular orbit experiences a centripetal acceleration of 8.89 m/s ^2. the tangential speed of the satellite is 7.76 x 10 ^3 m/s. what is the altitude of the satellite? (rE= 6.38 x 10^6 m)

A child is holding a string with a ball tied at the end. The child spins around in a circle causing the ball to travel in uniform circular motion. While doing this, the 1.3 m long string makes a 48.8◦ angle below horizontal. What is the tangential speed of the ball?

A circular track has several concentric rings where people can run at their leisure. Phil runs on the outermost track with radius rP while Annie runs on an inner track with radius rA = 0.70 rP. The runners start side by side, along a radial line, and run at the same speed in a counterclockwise direction. How many revolutions has Annie made when Annie's and Phil's velocity vectors point in opposite directions for the first time?

I need help on this question: You are driving on a horizontal circular road of radius 50.0 m at a constant speed of 11.17 m/s. How much time does it take to complete 10 rounds?What is your angular velocity? When you are at the northern most point on the road, what is the magnitude and direction of your acceleration?

A wheel of a radius 5.02 m rotates at a uniform speed. If a point on the rim of the wheel has a centripetal acceleration of 4.00 m/s2, what is the point’s tangential speed?

What is the radial acceleration of the blade tip expressed as a multiple of the acceleration due to gravity, g? Express your answer as a multiple of g.

The Mars Global Surveyor orbits Mars at an average altitude of 380 km. The average radius of Mars is 3390 km. If it takes the spacecraft 1.95 hours to complete one orbit around the planet, what is it's tangential velocity in kilometers per hour?
