What are quantum paths, and the path integral formulation of quantum mechanics?
A small block on a frictionless horizontal surface has a mass of 2.25×10?2kg . It is attached to a massless cord passing through a hole in the surface. (See the figure below (Figure 1) .) The block is originally revolving at a distance of 0.255m from..
A centrifuge rotor rotating at 10,344 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 3 m times N. The mass of the rotor is 4 kg and it can be approximated as a solid cylinder of radius 0.1 m. What is the kinetic..
A 4.0 kg box is initially at rest on a smooth surface. You then push on the box with a constant 200 N force to the right. How fast is the box moving after you've been pushing for 5.0 s?
You throw a softball straight upward with an initial speed of 5.0 m/s. Assume air resistance is negligible. How long does it take for the softball to reach its maximum height
neglect air resistance during the descent. she comes to rest 3 m under the surface of the water. Find out the average force that the water exerts on the diver
An aircraft has a lift-off of 120km/h. (a) What minimum constant acceleration does the aircraft require if it is to be airborne after a takeoff run of 240m (b) How long does it take the aircraft to become airborne
A man wishes to vacuum his car with a canister vacuum cleaner marked 535 W at 120 V. The car is parked far from the building, so he uses an extension cord 15.0 m long to plug the cleaner into a 120-V source. Assume that the cleaner has constant r..
If UV light with a wavelength of 250 nm shines on a zinc plate with a work function of 4.31 eV, Find the KE in eV of the ejected electrons
While you are traveling in a car on a straight, levelinterstate highway at 90 km/h, What is your velocity relative to the other driver
Dirk pushes on a packing box with a horizontal force of 52.0 N as he slides it along the floor. How much total work is done on the box in moving it 3.20 m along the floor
Ordinary glasses are worn in front of the eye and usually 2.00cm in front of the eyeball. What is their power in diopters
A 4.0 g bullet is fired into a 0.40 kg block attached to the end of a 0.60 m nonuniform rod of mass 0.50 kg. The block-rod-bullet system then rotates in the plane of the figure about a fixed axis at A.
