The speed of a 110-g toy car at the bottom of a vertical circular portion of the track is 8.25 m/s. If the radius of curvature of this portion of the track is 57.5 cm, what are the magnitude and direction of the force the track exerts on the car? (assume the car's path is in the clockwise direction.)?
A hockey puck with mass 0.163 kg is pushed across the ice with a constant force of 0.37 N. The coefficient of kinetic friction between the puck and the ice is 0.13.
After a distance of 1.3 m, what is the puck's speed in m/s?
A daredevil is going to ride her rocket-powered motorcycle through a circular loop-the- loop which has a 3.0 meter radius. She has 50.0 meters to get up to speed before going into the loop. Assuming there is no friction or air resistance, what maximum force must be applied to the motorcycle over the 50.0 m in order for her to make it through the loop without losing consciousness? Most humans can experience accelerations up to 3g before losing consciousness. Assume the combined mass of the rider and motorcycle is 250 kg. I keep getting 367N but the study guide says 510 N (rounded from 514.5 N)
