A 5 lbs hammer is lying at the bottom of an empty well that is 16 ft deep. A rope weighing 1/16lb/ft is used to lift the hammer to the surface. How much work is done? (ans: 88 ft-lb)
The maximum strain of a steel wire with Young's modulus 2.0 x 10^11 N/m^2, just before breaking, is 0.20%. What is the stress at its breaking point
A monatomic ideal gas that is initially at a pressure of 1.60 x 105 Pa and with a volume of 8.50 x 10-2 m3 is compressed adiabatically to a volume of 4.10 x 10-2 m3. How much work is done by the gas during the compression
A car of mass = 1200 traveling at 65 enters a banked turn covered with ice. The road is banked at an angle , and there is no friction between the road and the car's tires. What is the radius of the turn if = 20 (assuming the car continues in unifo..
On an old-fashioned rotating piano stool, a woman sits holding a pair of dumbbells at a distance of 0.650m from the axis of rotation of the stool. Compute the kinetic energy of the system after the dumbbells are pulled in
An object attached to a horizontal spring is oscillating back and forth along a frictionless surface. The maximum speed of the object is 1.75 m/s, and its maximum acceleration is 7.79 m/s2. How much time elapses betwen an instant when the object's sp..
200 grams of ice at -20°C are added to 500 grams of water at +80°C. Assuming that no heat is lost from the ice+water system, compute how much ice remains at equilibrium.
