A skier of mass 85.0 kilogram is pulled up a snow-covered slope at a constant speed by a tow rope that is parallel to the ground. The ground slopes upward at a constant angle of 28.0o above the horizontal and you can neglect friction.
1.) Draw a free body diagram of the skier?
2.) Find what is the tension of the tow rope?
A wedge of mass m=36.1 kg is located on a plane that is inclined by an angle ?=21.3 degrees with respect to the horizontal. A force F=302.3 N in the horizontal direction pushes on the wedge. The coefficient of kinetic friction between the wedge and t..
As a city planner, you receive complaints from local residents about the safety of nearby roads and streets, Given that the goal is to allow all vehicles to come safely to a stop before reaching the intersection, calculate the maximum desired speed ..
Discover the maximum net charge that can be placed on a spherical conductor of radius 24 cm before dielectric breakdown of the air occurs. What is the potential of the sphere when it carries this maximum charge?
A cylinder containing an ideal gas has a volume of 2.0 m3 and apressure of 1.0 × 105 Pa at a temperature of 300 K. Thecylinder is placed against a metal block that is maintained at 900K and the gas expands as the pressure remains constant until th..
An 75.0-N crate of apples sits at rest on a ramp that runs from the ground to the bed of a truck. The ramp is inclined at 30.0° to the ground. What is the direction of the contact force
You ski straight down a 44.4° slope, starting from rest and traveling a distance of 12.3 m along the slope. Find your final velocity
Although all atoms have moving electric charges, not all materials are magnetic (for example, copper or wood are not magnetic). Why, then, aren't all materials magnetic?
Assume the speakers are reconnected so that the 440 Hz sounds they emit are accurately out of phase. At what positions (how far should the microphone be moved to the right) are the intensity maximum and minimum now.
An illusionist causes a valuable piece of jewelry apparently to disappear by dropping it in a pool of water directly under the center of a circular platform floating on the surface. Find the minimum diameter of the platform that would prevent the ..
