A person pulls a 5.0 kg sled by a rope across a floor. The coeffecient of kinetic friction between the floor and the sled is 0.15. The rope (and therefore the force) is oriented 22 degrees above the horizontal. The magnitude of this force is 25 N.
What is the horizontal acceleration of the sled?
What is the magnitude of the normal force?
If the ball was thrown from the street, when does it reach the street again after it passes by window on the way up.
A second baseman tosses the ball to first baseman, which catches it at the same level from which it was thrown. The throw is made with an initial speed of 15 m/s at an angle of 38.0^circ above the horizontal. What is the horizontal component of ba..
In a common but dangerous prank, a chair is pulled away as a person is moving downward to sit on it, causing the victim to land hard on the floor.
The small spherical planet called "Glob" has a mass of 6.06×1018 kg and a radius of 5.84×104 m. What was the initial speed of the rock as it left the astronaut's hand? (Glob has no atmosphere, so no energy is lost to air friction
A 1245-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A W = 1955-N crate hangs from the far end of the beam.
A bird is flying directly toward a stationary bird-watcher and emits a frequency of 1020 Hz. The bird-watcher, however, hears a frequency of 1060 Hz. What is the speed of the bird, expressed as a percentage of the speed of sound?
A physics professor is pushed up a ramp inclined upward at an angle 34.0 degrees above the horizontal as he sits in his desk chair that slides on frictionless rollers, Use the work-energy theorem to find his speed at the top of the ramp
The position and momentum of a 3.01 keV electron are simultaneously determined, what is the minimum percentage uncertainty in its momentum
An object with mass 4.0kg is executing simple harmonic motion, attached to a spring with spring constant 300N/m, Calculate the max speed obtained by the object
If 200 g of water is contained in a 300g aluminum calorimeter at 20°C and 20g of steam at 100°C is introduced into the calorimeter
The telescope at a small observatory has objective and eyepiece focal lengths respectively of 20.0 m and 12 cm. determine length of the barrel of the telescope
A constant torque of 21.4 N•m is applied to a grindstone whose moment of inertia is 0.125 kg•m2. Using energy principles, determine the angular speed (in revolutions per second) after the grindstone has made 19 revolutions. (Avoid friction.) Do no..
