A speed skater goes around a turn that has a radius of 31 m. The skater has speed of 14 m/s and experiences a centripetal force of 460 N. What is the mass of the skater?

You are speeding around a turn of radius 30.0 m at a constant speed of 15.0 m/s.  Assuming your mass is 75.0 kg, what is the centripetal force on your body? Express your answer in newtons.

On a typical road, the force of friction during a turn can be up to 195,000 N. If a car has a mass of 1050kg and makes a turn with a radius of 20.0m, how fast can it be going?

A 3.00 kg mass is placed on an incline of 35 degrees. What is the parallel component of the gravitational force directed down the incline?

A speed skater goes around a turn that has a radius of 31 m. The skater has a speed of 12 m/s and experiences a centripetal force of 450 N. What is the mass of the skater? Number i Units <

The passengers in a roller coaster feel 42 % heavier than their true weight as the car goes through a loop with a 30 m radius of curvature.  What is the car's speed at the bottom of the loop?  Use g = 10 N/kg.  Hint:  How heavy some one feels is another name for normal force.  The problem therefore tells you the normal force.  If you know weight and normal force, you can determine centripetal acceleration.  You can substitute a value for mass if you wish.

A 76kg satellite orbits a distant planet with a radius of 4300km and a period of 280 min. From the radius and period, you calculate the satellite's acceleration to be 0.60m/s^2. What is the gravitational force on the satellite?

A 100 g bolo is swung in a circle 60 cm in radius at a speed of 10 m/sec. What is the centripetal force exerted on the mass by the rope?
