A curve in a road forms part of a horizontal circle. As a

car goes around it at constant speed 14.0 m/s, the total

force on the driver has magnitude 130 N. What is the

total vector force on the driver if the speed is 18.0 m/s

instead?

A rough inclined plane, rises 1cm for every 5cm along the inclined length. Calculate the effort required to drag a body weighing 150 N up the plane, when the effort is applied parallel to the plane. Take coefficient of friction as 0.3.
