Find out the precession period of the axis
An electric force of 4.0 N exists between two objects separated from each other by a distance of r. If the distance is decreased to 0.50 r, compute the magnitude of the force between the two objects.
A 200g mass on the end of a spring is pulled back 3 cm and released. There is a coefficient of friction between the table and mass of 0.7. The resonant frequency is 7.071 rad/sec.
A 60.0 kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.760 and 0.410, correspondingly. What horizontal pushing force is required to (i) just start the crate moving and (ii) slide the crate ..
A tight guitar string has a frequency of 540Hz as its third harmonic. What will be its fundamental frequency if it is fingered at a length of only 56% of its original length?
The object to be viewed is placed 2mm beyond the focal point of objective lens. What is the overall magnification of this microscope.
Direction of the surface winds What is the expected composition
Two non conservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. What is the transform in the car's kinetic energy, ΔKE = KEf - KE0, from A to B.
Speedboat A negotiates a curve whose radius is 150m. Speedboat B negotiates the curve whose radius is 190m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
An underwater diver sees the sun 55 degrees above horizontal. How high is sun above the horizon to a fisherman in a boat above the diver.
A cylinder is rolling along the ground without the slipping at 7m/s. It comes to a hill and begins going up. Assume no losses to friction, how high vertically would it go before it stops?
Starting from rest, a 98 kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a magnitude of 800N, and his speed at the bottom of the pole is 3.2 m/s. How far did he slide down the pole.
