Two blocks of identical wood sit on slippery (no friction) ice. You fire a bullet at each block. At the first block, you fire a metal bullet that impales itself in the block. At the second block, you fire an equal-mass, equal-speed rubber bullet that bounces straight back from the wood block. Which wood block if either will have the greatest speed after the collisions? Please explain your reasoning!
A capacitor is connected across the terminals of an ac generator that has a frenquency of 460 Hz and supplies a voltage of 24 V. When a second capacitor is connected in parallel with the first one, the current from the generator increases by 0.18 A. ..
An energetic father stands at the summit of a conical hill as he spins his 21 child around on a 5.1 cart with a 2.1--long rope. The sides of the hill are inclined at 25 . He keeps the rope parallel to the ground, and friction is negligible. What rope..
The magnetic field produced by the solenoid in a magnetic resonance imaging (MRI) system designed for measurements on whole human bodies has a field strength of 7.33 T, and the current in the solenoid is 2.20 x 102 A. What is the number of turns per ..
A block with mass m1 = 9.4 kg is on an incline with an angle ? = 24.0° with respect to the horizontal. For the first question there is no friction, but for the rest of this problem the coefficients of friction are: ?k = 0.23 and ?s = 0.253. * When th..
A box rests on top of a flat bed truck. The box has a mass of m = 16.0 kg. The coefficient of static friction between the box and truck is ?s = 0.81 and the coefficient of kinetic friction between the box and truck is ?k = 0.63. * The truck accele..
Suppose a star the size of our Sun (R0 = 695,500 km) rotates at a speed of 1.0 revolution every 12 days. If it were to undergo gravitational collapse to a neutron star of radius 11 km, what would its new rotation speed be? (rad/s)
Air is flowing at steady state through a 5 cm diameter pipe at a flow rate of 0.35 mole/min at P = 5 bar and T = 500 K. It flows through a throttle valve and exits at 1 bar.
Water is drawn from a well in a bucket tied to the end of a rope whose other end wraps around a solid cylinder of mass 50 kg and diameter 25 cm. As this cylinder is turned with a crank, the rope raises the bucket.
A projectile of mass m is fired from the ground with an initial speed vi at an angle of q above the horizontal. At the highest point of its arc, it explodes into three pieces, A, B and C, all of equal mass. Immediately after the explosion, pieces A a..
A firecracker resting on a level street explodes into three pieces of equal mass. Immediately after the explosion, the first piece is moving north at 125 m/s, and the second piece is moving east at 75.0 m/sec. What is the velocity of the third piece ..
