an artillery shell is fired with an initial velocity of 350 m/s at 50.0 degrees measured from the horizontal. it hits the side of a mountain 35.0 seconds later. What are the x and y coordinates of the shell where it explodes, if the coordinates from where it was fired are (0,0), and it was fired in the positive x direction?
A helicopter is ascending vertically with a speed of 5.45m/s. At a height of 141m above the Earth, a package is dropped from a window. How much time does it take for package to reach the ground.
A disk of radius R = 9 cm is pulled along a friction less surface with a force of F = 15 N by a string wrapped around the edge. At the instant when d = 28 cm of string has unwound off the disk, what is torque exerted about the center of the disk.
Three charges, +q, +2q, and +4q, are linked by strings (Assume that the middle charge is fixed in space and the other 2 charges are held there by the tension alone.)
A long, narrow rectangular loop of wire is moving toward the bottom of page with a speed of 0.025 m/s. The loop is leaving a region in which a 2.1 T magnetic field exists; magnetic field outside this region is zero. All through the time of 1.0 s, wha..
a block of mass m=0.2kg , in simple harmonic motion, has an amplitude of 3.5cm and a maximum speed of 70 cm/s. What is the angular frequency for the oscillation in rad/s?
What is the strength of an electric field at a distance r from the center, inside the sphere. Assume the sling thrower could gradually increase the speed of the stone.
A golf ball strikes a hard, smooth floor at an angle of 30 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.047 kg, its speed is 45 m/s just before and after striking the floor. What is the magnitude of the impuls..
If the weight of a room full of water is so great, why don't the first floors of houses built over basements all collapse as flooded to the ceiling.
While running, a person dissipates about 0.60 J of mechanical energy per step per kilogram of body mass. If a 64 kg person develops a power of 65W throughout a race, how fast is the person running? Assume that a running step is 1.5 m long.
A 25 kg child on a 2.0 m swing is released from rest when the swing supports make the angle of 30.0 degrees with the vertical.
A planet moves in an elliptical orbit around the sun. The mass of the sun is Ms. The minimum and maximum distances of the planet from the sun are R1 and R2, in that order.
A Carnot engine operates between temperatures of 747 and 324 K. Calculate what the efficiency would be if (a) the temperature of the hot reservoir were raised by 42.5 K or (b) if the temperature of the cold reservoir were lowered by 42.5 K. (Give ..
