A physics student needs to loosen a large lock bolt The bolt takes 1500N-m to break free and loosen. The student has a mass of 48Kg, and she has a 0.5m breaker wrench and three sections of pipe which may be attached to the wrench. The sections extend the wrench by 1m, 2m and 3m respectively. Can she loosen the bolt?
If so, how. (Ignore the mass of the wrench and the pipes) A 1,730 KG car traveling at a rate of 166Kph is racing around a flat circular track, maintaining a perfectly circular 2 Km path What is the centripetal force acting on the car? What is the minimum coefficient of statistic friction between the tires and the track that will maintain this situation? If the tiles have a radius of 1.2m, what is the angular velocity of the tire? How many rotations do the tiles make on a single loop around the track?
