A 53 kg woman and a 80 kg man stand 13 m apart on, Ask an Expert

Academics

Q. A 53 kg woman and a 80 kg man stand 13.0 m apart on frictionless ice. If they hold on to the two ends of a rope, and the man pulls on the rope so that he moves 3.0 m, how far from the woman will he be now?

Q. A car with a constant speed of 83km/h enters a circular flat curve with a radius of curvature of .50 km. Calculate centripetal acceleration of the car. If the coefficient of friction between tires and road is 1.2, then will the car stay on road or will it skid off the road.
