Describe how to find moment of inertia. Provide equations allowing to find moment of inertia of a solid cylinder and of a cylindrical ring.
A 0.525 kg ball starts from rest and rolls down the hill with uniform acceleration, travelling 150 m throughout the second 10.0 rm s of its motion.
An elevator weighing 2500 N ascends at a constant speed of 8.0 m/s. How much power must the motor supply to do this?
When she tightens the string slightly, she hears 6 beats/s. What is the frequency of string now.
How will their speeds to relate to each other when they land? Ignore air resistance. Clarify with graph. Draw a graph and explain why it happens.
A transverse wave travels on a string of length 1.3 m and diameter 1.1 mm, What is the linear mass density of the string
At its Ames Research Center, NASA uses its large "20-G" centrifuge to test the effects of very large accelerations (hypergravity) on test pilots and astronauts. In this device, an arm 8.84m long rotates about one end in a horizontal plane, and the..
A stick of mass m and length L spins with frequency w around an axis, What is the tension in the string, and what is the force that the pivot applies to the stick
The horizontal surface is frictionless and the system is free from rest. Using energy concepts, determine the speed of m3 after it moves down a distance of 6.0 m.
A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 16.0° below the horizontal. The length of time the car is in the air
An airplane pulls a 24 kg banner on a cable as depicted in the figure below. When the plane has a constant cruising velocity the cable makes an angle of ? = 26°
A child slides down a slide with the 29 degree incline, and at the bottom her speed is precisely half of what it would have been if the slide had been frictionless. Compute the coefficient of sliding between the child and the slide.
An automobile has a total mass of 1700 kg. It accelerates from rest to 40 km/h in 10 s. Assume each wheel is a uniform 32 kg disk. determine the total kinetic energy of the automobile
