A 7.8 g bullet moves horizontally with speed of 200 m/s and embeds in a 1.7 kg block resting on a horizontal surface having a coefficient of friction of 0.18. Determine the distance (in m) that the block will slide before coming to rest.
The conducting rod shown in Fig. 30-50 has length L and is being pulled along horizontal, frictionless, conducting rails at a constant velocity. At what rate does this force do work on the rod
A ball of mass 0.640 kg moving east (+x direction) with a speed of 3.20 m/s collides head-on with a 0.480 kg ball at rest. If the collision is completely elastic, what will be the speed and direction of each ball after the collision?
A 520 turn circular-loop coil 14.5 cm in diameter is originally aligned so that its axis is parallel to Earth's magnetic field. In 2.82 ms the coil is flipped thus that its axis is perpendicular to the Earth's magnetic field.
