Question
Thearea under the curve on a Force versus time (F vs. t) graph represents Find the net work done by friction between the ground and the body of a snake slithering in a complete circle of 1.95 m radius. The coefficient of friction between the ground and the snake is 0.25, and the snake's weight is 75.0 N. A roadway is designed for traffic moving at a speed of 57 m/s. A curved section of the roadway is a V circular arc of 240 m radius. The roadway is banked-so that a vehicle can go around the curve with the lateral friction forces equal to zero. The angle at which the roadway is banked is closest You are standing on a skateboard, initially at rest. A friend throws a very heavy ball towards you. You can either catch the object or deflect the object back toward your friend (such that it moves away from you with the same speed as it was originally thrown). What should you do in order to maximize your speed on the skateboard?Explanation / Answer
