If the bullet lodges in the rod and the angular velocity of the rod is 9.0 rad/s immediately after the collision, what is the magnitude of the bullet's velocity just before impact?
The coffcient of kinetic friction between the block and the incline is 0.1. The block is initially at rest. What is the kinetic energy of the block after it has been displaced 2 m along the incline?
Find the electric field magnitude and direction (a) at the center of the square, (b) at the point (-a, -a), and (c) at the point (1/2a, 0). In each case state which protons contribute to the field you compute and which cancel.
A .5 m length of rigid metal rod is connected through two springs ( with 10 N/m spring constants) perpendicular to the rod at either end, to a circuit that supplies 2.5 A of current through the wire. If the rod is perpendicular to a uniform 2 T m
A space traveler weighs 550 N on earth. What will the traveler weigh on another planet whose radius is three times that of earth and whose mass is twice that of earth?
Calculate the theoretical phase difference (in degrees) between the current CPA and voltage VPB if the circuit is driven by a sinusoidal voltage source with a peak amplitude of 4.6 V at the following frequencies:
You need to design a 60.0-Hz ac generator that has a maximum emf of 5600 V. The generator is to contain a 170-turn coil that has an area per turn of 0.96 m2. What should be the magnitude of the magnetic field in which the coil rotates?
A hare and a tortoise compete in a race over a straight course 1.25 km long. The tortoise crawls at a speed of 0.300 m/s toward the finish line.
A person stands on a scale in an elevator. As the elevator starts, the scale has a constant reading of 598 N. As the elevator later stops, the scale reading is 392 N. Assume the magnitude of the acceleration is the same during starting and stoppin
