Q. A 60.0 kg crate is slid up an inclined ramp 2.0 m long onto a platform 1.6 m above the floor level. A 452 N force, parallel to the ramp, is needed to slide the crate up the ramp at a constant speed. How much work is done in sliding the crate up the ramp?
Q. A 10g bullet is fired into a 100g block of wood at rest on a horizontal surface. After impact, the block slides 8m before coming to rest. If the coefficient of friction is .6, find the speed of the bullet before impact.
Define Eddy viscosity and Von Karman constant using the mixing-length theory.
Presume the child remains horizontal during the fall to the floor. Note that a more complicated fall could result in a head velocity greater or less than the speed you calculate.
A potter's wheel having a radius 0.47 m and a moment of inertia 10.9 kg•m2 is rotating freely at 46 rev/min. The potter can stop the wheel in 7.0 s by pressing a wet rag against the rim and exerting a radically inward force of 68 N. Find out the effe..
