Q. Grains of sand of mass 2.70 10-3 g each, fall from a height of 0.9 m on a sticky surface at a rate of 56 grains per second per cm2. What pressure does this shower of sand exert on the surface, assuming that air resistance can be neglected?
Q. Assume that at some point just outside the surface of the conductor, the electric field has magnitude and is directed toward the surface of the conductor. What is the charge density on the surface of the conductor at that point?
If a car traveling at 55 km/h will skid 24 m while its brakes lock, how far will it skid if it is traveling at 130 km/h when its brakes lock.
A slab of marble is resting on the ground. It weighs 600 N and has the dimensions 0.1m x 0.2m x 1.0m. What is the greatest pressure that the slab can exert on ground.

A particular freely falling object requires 1.95 s to travel the last 33.5 m before it hits the ground. From what height above the ground did it fall.
Suppose that the speed of the water in the reservoir is zero, and that the water flow is steady. Overlook both air resistance and the height difference between the reservoir and the muzzle.
An indestructible bullet 1.85 cm long is fired straight through a board that is 11.10 cm thick. The bullet strikes board with a speed of 455m/s and emerges with a speed of 279m/s. (To simplify, suppose that the bullet accelerates only while the fr..
An apple drops from the tree and falls freely. The apple is originally at rest a height {H0} above the top of the grass of a thick lawn, which is made of blades of grass of height {h}. When apple enters the grass, it slows down at a constant rate ..
A vessel whose walls are thermally insulated contains 2.3 kg of water and 0.35 of ice, all at the temperature of 0.0 . The outlet of a tube leading from a boiler in that water is boiling at atmospheric pressure is inserted into the water. How many..
A rifle with a barrel length of 57 fires an 11 bullet with a horizontal speed of 440. The bullet strikes a block of wood and penetrates to a depth of 12. What resistive force (assumed to be constant) does the wood exert on bullet.
