8) A marble moving 1.48 m/s rolls off the top edge of a 125. cm high table.
(a) How far from the base of the table did it strike the floor?
(b) How long was it "in flight"?
A 1.2kg block slides along a frictionless surface at 1.5m/s . A second block, sliding at a faster 4.8m/s, what is the mass of the of the second block
An airtight box has a removable lid of area 1.10 multiplied by 10-2m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.80 multiplied by 105 Pa.
Coherent light with wavelength 546 nm passes through two very narrow slits, and the interference pattern is observed on a screen the distance of 3.00 {rm m} from the slits. The first-order bright fringe is a distance of 4.86 {rm mm} from the center o..
How fast can this car round a second curve of radius 320m?
An initially stationary 2.0 kg object accelerates horizontally and uniformly to a speed of 20 m/s in 1.9 s. (a) In that 1.9 s interval, how much work is completed on the object by the force accelerating it.
Find out the speed of the satellite
describes the net gravitational force on the particle due to the shell? zero if the particle is at the center of the shell but nonzero at other locations within the hollow zero for any location of the particle within the hollow.
A child's toy consists of a piece of plastic attached to a spring. The spring is compressed against the floor a distance of 1.2 cm, and the toy is released. If the spring constant is 103 N/m, what is the magnitude of the spring force acting on the..

An alert physics student stands beside the tracks as a train rolls slowly past. He notes that the frequency of the train whistle is 445 Hz, calculates the speed of the train
A toy train is pushed forward and released at xi = 1.60 m with a speed of 2.60 m/s. It rolls at a steady speed for 1.30 s, and then one wheel begins to stick. The train comes to a stop 6m from its starting point. What is the train's acceleration a..
A 2.10 x 10^3 kg car starts from rest at the top of a 4.70 m long driveway that is inclined at 25° with the horizontal. If an average friction force of 4.0 x10^3 N impedes motion, find out the speed of the car at the bottom of the driveway.
