1. A 1000kg convertible on the way to Pikes Peak stops on a 14.1% incline. Calculate the friction force between the tires and the road and the minimum coefficient of friction necessary to keep the car from sliding down the hill.
2. A 5000kg truck is being pulled up a 15 degree ramp by a cable which is parallel to the surface of the ramp. If the coefficient of friction u between the wheels of the truck and the ramp is 0.100 and the truck is being pulled at a constant velocity, calculate the tension in the cable.
3. A 500kg vehicle is being driven up a 10 degree slope, propelled by a 2500N force acting parallel to the road surface.
What is the maximum speed with which a 1060kg car can round a turn of radius 75m on a flat road if the coefficient of static friction between tires and road is 0.80.
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26 , starting fro..
A mass spectrometer has an adjustable magnetic field. When themagnetic field is 7.000e-2 T, a singly ionized hydrogen atom (a proton) will strike the detector at a particular location. Suppose a triply-ionized carbon 12 atom, whose mass is by defi..
