A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (3.01 m, 4.12 m) while a constant force acts on it. The force has magnitude 1.54 N and is directed at a counterclockwise angle of 100° from the positive direction of the x axis. How much work is done by the force on the coin during the displacement?
An airplane is flying with the velocity of 82.0 at an angle of 22.0 above the horizontal. When the plane is a distance 111 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog..
A uniform electric field of magnitude 271 V/m is directed in the negative x direction. A +12.7 ?C charge moves from the origin to the point (x, y) = (15.5cm, 46.0 cm). What was the change in the potential energy of this charge?
business equipment for a $5,000 loss, stock investment for a $7,000 loss, and her principal residence for a $16,000 loss. Presuming adequate income, explain how much of these losses may Joan claim on her 2011 return?
Four identical charges (+2.2 ?C each) are brought from infinity and fixed to a straight line. Determine the electric potential energy of this group

A radar receiver can be tuned to detect signals in the range of [1750 µm to 2750 µm]. What is the frequency difference between the minimum and maximum wavelength
You find an unlabeled box of fine needles, and want to determine how thick they are. A standard ruler won't do the job, since all you can tell is that each needle is less than a millimeter thick.
Four identical cells, each of emf 2V are joined in parallel providing supply of current to external circuit consisting of two 15 ohm resistors joined in parallel, Calculate the internal resistance of each cell
At the instant the car begins to accelerate, a truck with a constant velocity of 21 m/s passes in the next lane. Explain how far will the car travel before it overtakes the truck?
