A flat cylindrical grinding wheel is spinning at 2000 rpm (clockwise when viewed head-on) when its power is suddenly turned off. Normally, if left alone, it takes 45.0 s to coast to rest. Assume the grinder has a moment of inertia of 2.43 kg-m2.
(a) Determine its angular acceleration during this process.
(b) Determine the tangential acceleration of a point on the grinding wheel if the wheel is 7.5 cm in diameter.
(c) The slowing down is cause by a frictional torque on the axle of wheel. The axle is 1.00 cm in diameter. Determine the frictional force on the axle.
(d) How much work was done by friction on the system?
A car of mass M = 800kg travelling at 50km/hour enters a banked turn covered with ice. The road is banked at an angle 20degrees, and there is no friction between the road and the car's tires.
A positive charge of 0.800? C is located in a uniform field of 1.20×105 N/C. A negative charge of -0.400? C is brought near enough to the positive charge that the attractive force between the charges just equals the force on the positive charge du..
A ray of light incident upon a mirror makes an angle of 42 with the mirror. What is an angle between the incident ray and the reflected ray.
A car is traveling at 43.2km/hr on a flat, concrete highway. If the brakes are applied such that skidding occurs, the kinetic coefficient of friction between the road and tires is 0.808. If anti-lock brakes are properly applied after that no skidd..
The Royal Gorge bridge over the Arkansas River is 360 m above the river. A bungee jumper of mass 93 kg has an elastic cord of length 85 m attached to her feet. Find the maximum speed of the jumper
The escape speed from the Earth is 1.12 × 10^4 m/s, so a gas molecule traveling away from Earth near the outer boundary of the Earth's atmosphere would, at this speed, be able to escape from Earth's gravitational field.
Traffic is moving along the highway at 51 km/h on a rainy day. Illustrate what is the minimum coefficient of friction between tires and road that will allow cars to negotiate the turn without sliding off the road?
What is the wavelength of the second laser that would place its second maximum at the same location as the fourth minimum of the first laser, if = 0.300 ?
A 1300 {rm N} crate slides 13 {rm m} down a ramp that makes the angle of 30^circ with the horizontal. If the crate slides at a constant speed, how much thermal energy is created.
On a cool morning, when the temperature is 11 ^circC, you measure the pressure in your car tires to be 30.0 psi. After driving 20 mi on the freeway, the temperature of your tires is 53 ^circC.
A Norwich MCE student is involved in a crucial out of class experiment. He is in his dorm room 34 feet above an historic rock wall. Describe the final result and state any assumptions that you need to make. Would the final result be any different o..
A physics book slides off a horizontal table top with a speed of 1.00m/s. It strikes the floor after a time of 0.390ss, Find the height of the table top above the floor
