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?

The radius of Mars is about 3376 km, and its mass about 0.1 times that of the earth. What will be the velocity of a satellite circling Mars at a distance of 10 000 km from the centre of the planet?

Two satellites are in orbit around the earth at the same altitude (distance from center of earth), and have the same orbital period. But one satellite is twice as massive as the other satellite.   Which statement below is true?   The satellites have the same centripetal acceleration, but the more massive satellite has a larger centripetal force.   Neither object has a force acting on it because they're in space.   The centripetal forces are the same because they are moving the same.   The more massive satellite has a larger acceleration, and therefore a larger centripetal force.

And don't worry about whether the passengers would actually survive the trip. They are lightweight crash test dummies. NTC A cart of mass m= 347 kg is going around a circular loop-the-loop. There is no motor. The cart moves only under the influence of gravity. Ignore friction and let g = 9.81 meters per second squared. The loop has a radius of r meters. When the cart is at the top of the loop, the normal force on the cart (exerted by the track) pushes down on the cart with a force of N = 1,330 newtons. When it is at the bottom of the loop, the cart has a speed of 30.7 meters per second. What is the radius of the loop (in units of meters)?

A car of mass 1800 kilograms passes over a hill that has an arc with a radius of 42 meters. If the car is moving with a speed of 16 meters / second at the top of the hill, what g-force does the car experience?

A roller coaster car is going over the top of a 17-m-radius circular rise. At the top of the hill, the passengers "feel light," with an apparent weight only 60 % of their true weight. How fast is the coaster moving?

An m= 1,070 kg car passes over a hump with a velocity of v =12.1 m/s in a road that follows the arc of a circle of radius r =66 m. Find the normal force that the road exert on the car as the car passes the lowest point of the hump in units of N (Newton). Take g=9.8 m/s2, and round off your result to 1 decimal place.

A 0.7-kg mass attached to the end of a string swings in a vertical circle (radius = 2.3 m). When the mass is at the lowest point on the circle, the speed of the mass is 15 m/s. What is the magnitude of the force of the string in newtons (i.e. tension in the string) on the mass at this position?

A 1,669 kg automobile is moving at a maximum speed of 27 m/s on a level circular track of radius 88 m. What is the coefficient of friction?

A child moves with a speed of 1.50 m/s when 9.0 m from the center of a merry-go-round. Calculate the centripetal acceleration of the child and the net horizontal force exerted on the child (m = 25.0 kg).
