A puck slides across a smooth, level tabletop at height H at a constant speed vo. It slides off the edge of the table and hits the floor a distance x away as shown in the figure. What is the algebraic relationship between the distances x and H?
An Automobile engine slows down from 4500 rpm to 1200 rpm in 2.50 s. Calculate (a) its angular acceleration, assumed constant and (b) total number of revolutions the engine makes in this time.
An 82 kg lumberjack stands at one end of a 355 kg floating log. Both the log and the lumberjack are at rest initially. If the lumberjack now trots toward the other end of the log with a speed of 2.70 m/s relative to the log, what is the lumberjack's ..
An oil film with n = 1.45 floats on water. It is illuminated by white light from the sun at noon. If the film is 280 nm thick, find the wavelength and color of visible light that is most strongly reflected upward to an observer positioned above th..
A boat moves relative to water with a velocity which is n =2 times less than the river flow velocity. At what angle to the stream direction should the boat move to minimize drifting.
An airplane starting from airport A flies 280 km east, then 365 km at 29.0° west of north, and then 130 km north to arrive finally at airport B.
Two stationary positive point charges, charge 1 of magnitude 3.55 and charge 2 of magnitude 2.00 , are separated by a distance of 30. An electron is released from rest at the point midway between the two charges, and it moves along the line connec..

Two speakers, one directly behind the other, are each generating a 295-Hz sound wave. What is the smallest separation distance between the speakers that would produce destructive interference at a listener standing in front of them? Take the speed..
A positively charged rod is brought close to one end of an uncharged metal rod but does not actually touch it. What type of charge does the end of the metal rod closest to the positively charged rod acquire?
A bullet of mass 0.0022 kg initially moving at 503 m/s embeds itself in a large fixed piece of wood and travels 0.71 m before coming to rest. Assume that the acceleration of the bullet is constant.
Rank the magnitudes of the forces exerted on the following particles from largest to smallest. In your ranking, display any cases of equality. (Use only ">" or "=" symbols. Do not contain any parentheses around the letters or symbols.)
A bat strikes a 182g ball with a force of 109-N at an angle of 57° above the horizontal. What is the ball's vertical acceleration (positive for upward, negative for downward).
