A mass vibrates at the end of a spring with simple harmonic motion. The spring constant is 30 N/m. The maximum displacement of the mass from its equilibrium position is 20 cm. What is the kinetic energy of the mass when it is at half its amplitude?
Kris contributed property with a FMV of $90,000 and a basis of $35,000. Pasha has a 10% interest in the partnership and Kris has a 90% interest. Illustrate what is Pasha's basis in the partnership as of December 31?
The bullet strikes a block of wood and penetrates to a depth of 15 cm. What resistive force (assumed to be constant) does the wood exert on the bullet? Explain how long does it take the bullet to come to rest?
Note down that since each oscillator is attached to two "springs", and each "spring" is half the length of the interatomic bond, the effective interatomic spring stiffness for one of these oscillators is times estimated value given above.
A car of mass 1800 travelling at 60.7 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. Use = 9.80 throughout the problem.
Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +3q. Sphere B carries a charge of -q. Sphere C carries no net charge.
A movable piston having a mass of 7kg and a cross-sectional area of 6 cm2 traps 0.2 mol of an ideal gas in a vertical cylinder. The piston slides without friction in the cylinder. The outside of the cylinder is kept at atmospheric pressure, 1.013×..
