Q1. A dog pulls on the pillow with a force of 8.6 N at an angle of 22° above the horizontal. What is the forward or x component of this force?
Q2. For the Atwood's machine, suppose the masses have an initial speed of v = 0.22 m/s and that m2 is moving upward. How high does m2 rise above its initial position before momentarily coming to rest, given that m1 = 3.5 kg and m2 = 3.1 kg?
A 600 turn solenoid, 25 cm long, has a diameter of 2.8 cm. A 10 turn coil is wound tightly around the center of the solenoid. If the current in the solenoid increases uniformly from 0 to 5.0 A in 0.48 s, what would be the induced emf magnitude in the..
