Suppose a rubber stopper of mass 0.020 kg is attached to a string and revolving with constant speed of 4.0 meters/second about a horizontal circular path of radius 0.25 meters. What is the magnitude of the centripetal force on the rubber stopper?

A race car rounds a curve at 59 m/s. The radius of the curve is 417 m, and the car's mass is 620 kg. (Assume the car's speed remains constant. Take the radially inward direction to be positive. Indicate the direction with the sign of your answer.) (a) What is the car's (centripetal) acceleration? _______________m/s2What is it in g's? __________g(b) What is the centripetal force acting on the car? ______________N

A car with a mass of 1285 kg drives around a circular curve in the road with a 26.2 m radius of curvature at a constant speed of 14 m/s. What is the magnitude of the centripetal force acting on the car?

A car is moving on a banked curve at a speed v. A car is moving on a circular (radius = R) banked track (banking = B = 10° with respect to the horizontal) at a constant speed, v, in a circular path of radius R. A normal force, n, is exerted on the car from the track. The centripetal force is equal to the total normal force 0000 the radial component of the normal force the vertical component of the normal force none of the above
