As your plane circles an airport, it moves in a horizontal circle of radius 2500 meter with a speed of 400 km/h. If the lift of the airplanes wings is perpendicular to the wings, obtain at what angle should the plane be banked therefore that it doesn't tend to slip sideways?
Near the surface of the Earth, a car is traveling at 15 m/s on a horizontal road. The brakes are applied and the car skids to a stop in 4.0 s. discover the coefficient of kinetic friction among the tires and the road.
A 250g ice cube at -10?C is placed in an aluminum cup whose initial temperature is 70?C. The system comes to an equilibrium temperature of 20?C
A skier starts from rest at the top of a hill that is inclined at10.4°with the horizontal. The hillside is 245 m long, and the coefficient of frictionbetween snow and skis is 0.0750. At the bottom of the hill, thesnow is level and the coefficient ..
