Q. In a popular amusement park ride, the rotating cylinder of radius 3.0 m is set in rotation at an angular speed of 7.0 rad/s. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider's clothing and the wall is needed to keep rider from slipping? (Hint: Recall that the magnitude of the maximum force of static friction is equal to µn, where n is normal force - in this case, the force causing the centripetal acceleration.)
An electron moves in the positive x-direction a distance of 2.38 m in 2.95 x10-8 s, bounces off a moving proton, and then moves in the opposite direction a distance of 1.63m in 3.53x 10-8 s.
A 0.5kg block is attached to a spring with spring constant 18 N/m. As the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 34cm/s.
Thermal energy can shift some of the electrons in a hot semiconductor from valence levels to conduction levels. What effect do these shifts have on the semiconductor's ability to conduct electricity.
A 110kg clock initially at rest on a horizontal floor requires a 607N horizontal force to set it in motion. After the clock is in motion, horizontal force of 525 N keeps it moving with a constant velocity.
A 92 kg man standing on a surface of negligible friction shoves a 73 g stone lying at his feet, giving it a velocity of 4.0 m/s. What velocity does the man acquire as a result.
A 56 kg astronaut floating at rest in space outside a space capsule throws his 0.50kg hammer such that it moves with the speed of 14.00 m/s relative to the capsule. What happens to the astronaut? What is the astronaut's speed.
What minimum constant acceleration does this need if the aircraft is to be airborne after a takeoff run of 250 m.
The lens has a refractive index of 1.30. Find out the difference Δx in the positions where each crosses the principal axis.
At 18°C, a rod is exactly 20 cm long on a steel ruler. Both the rod and the ruler are placed in an oven at 285°C, where the rod now measures 20.21 cm on the same ruler. What is the coefficient of linear expansion for the material of which the rod ..
