Q. A 0.105kg hockey puck moving at 24 m/s is caught and held by a 68.00 kg goalie at rest. With what speed does the goalie slide on ice?
Q. For a damped oscillator with a mass of 360 g, a spring constant 110 N/m and a damping coefficient of 87.00 g/s, what is the ratio of the amplitude of damped oscillations to the initial amplitude at the end of 28 cycles?
Two objects have masses m and 5m respectively.They both are placed side by side on a frictionless inclined plane and allowed to slide down from rest.
A square, single turn coil 0.20m on a side is placed with its plane perpendicular to a constant magnetic field. An emf of 18mV is induced in the coil winding as the area of the coil decreases at the rate of 0.10m2/S. What is the magnitude of the m..
Find the recoil speed of the rifle. A 650-N force acts in a northwesterly direction. A second 650-N force must be exerted in what direction so that the reultant of the two forces points westward? Illustrate your answer with a vector diagram.
A stunt pilot performs a circular dive of radius 715m. At the bottom of the dive pilot has a speed of 265 m/s which at that instant is increasing at a rate of 15 m/s2(along the direction of vector B) What total acceleration does the pilot have at ..
A soccer ball with a mass of 448g bounces off the crossbar of a goal and is deflected upward at an angle of 56.2° with respect to horizontal. Immediately after deflection, the kinetic energy of the ball is 47.70 J. What are the vertical and horizo..
A 15m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes 60 angles with the horizontal.
Compute the final equilibrium temperature.
What will transform in terms of the observable properties of the black hole as this process continues
A small 15{rm g} bug stands at one end of a thin uniform bar that is initially at rest on a smooth horizontal table. The other end of the bar pivots about a nail driven into the table and can rotate freely, without friction.
Cowboy Joe wishes to shoot his assailant by ricocheting a bullet off the mirrored metal plate. To do so, should he simply aim at the mirrored image of his assailant.
An proton (m = 1.67 ´ 10-27 kg and q = 1.6 ´ 10-19 C) travelling at 2.7 × 105 ms-1 enters a magnetic field of 1.2 T at right angles to the direction of motion of the electron. What is the centripetal force on proton.
