Q. A high-speed flywheel in a motor is spinning at 450 when a power failure suddenly occurs. The flywheel has mass 38.0 and diameter 78.0 . The power is off for 25.0 and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 170 complete revolutions. At what rate is the flywheel spinning when the power comes back on?
Q. The human eye is sensitive to orange light having a frequency of about 5.0 1014 Hz (a wavelength of about 608 nm). What is the energy in joules of the photons associated with this light?
A box of books weighing 334 N is shoved across the floor by a force of 479 N exerted downward at an angle of 33° below the horizontal. What is the maximum coefficient of kinetic friction between the box and the floor that allows the box to move with ..
A 1500 {rm kg} car skids to the halt on a wet road where mu_k = 0.50. How fast was the car travelling if it leaves 66-{rm m}-long skid marks.
The springs of a 1600 kg car compress 5.0 mm when its 65 kg driver gets into the driver's seat. If the car goes over a bump, what would be frequency of vibrations.
Two identical speakers are driven by the same oscillator @ 200Hz. They are located on a vertical pole & 4.00 m apart. A man walks straight towards the lower speaker perpendicular to the pole.
Two points are located on a rigid wheel that is rotating with an increasing velocity about fixed axis. The axis is perpendicular to the wheel at its center. Point 1 is located on the rim and point 2 is halfway between rim and axis .at any given insta..
An airplane is flying with a velocity of 86.0 at an angle of 23.0 above the horizontal. When the plane is a distance 114 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
Due to the nature of the wastewater, the engineer wants to target the high end of this range. Find the proper diameter pipe to the nearest 2” (e.g., 2”, 4”, 6”, 8”, 10”, etc.) to achieve this design objective.
If John Glenn weighed 640 N on Earth's surface, a) how much would he have weighed if his Mercury spacecraft had (hypothetically) remained at twice the distance from centre of Earth? b) Why is it said that an astronaut is never truly "weightles".
A bicycle and rider have a combined mass of 100 kg. How many calries of heat are generated in brakes when the bicycle comes to a stop from a speed of 36 km/h.
A 33.0 g bullet moving at 434 m/s strikes a 5.0 kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 295 m/s. How fast is the bag moving while the bullet exits.
The coefficient of static friction between the wall and the rod is μs = 0.575. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A.
