Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holy Compton designed a speed bump (called the Holly Humo) and had it installed. Suppose 1000-kg car passes over a hump In a roadway that follows the art of a circle of radius 18.4 m as in the figure below (a) of the car travels at 28.8 km/h what force does the road exert on the car as the carpasses the highest point of the hump? magnitude direction (b) What...

Suppose a 1,850-kg car passes over a bump in a roadway that follows the arc of a circle of radius 22.0 m as in the figure shown below. A car traveling to the right over a hump on the road at a velocity vector v. (a) What force does the road exert on the car as the car passes the highest point of the bump if the car travels at 8.30 m/s? (Neglect any friction that may occur.) magnitude__________ kN...

1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
