A large wheel starts from rest and has a constant angular acceleration of 3.5 radians/second^2. After 12 seconds the wheel has an angular velocity of 42 radians/second. The torque required to produce this motion is 1570 Newton meter. Determine the total angular displacement of the wheel during this motion.
Consider an angular motion. If the displacement is given as 250teθ, and the radius r is constant, derive the expressions for the angular velocity θ=ω, angular accelerationα, linear displacements, linear velocitytv, normal accelerationna, and tange..
What is the average induced EMF. what is the magnitude of the velocity of raindrops relative to the car.
Arlene is to walk across a high wire strung horizontally between two buildings 11.0 m apart. The sag in the rope when she is at the midpoint is 10.0°. If her mass is 56.0 kg, what is the tension in the rope at this point.
The partnership earnings before partners' withdrawals for 2005 totaled $484000. Calculate José's gross income from the partnership from the above for 2005.
Two people with a combined mass of 120kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 8.30 cm. When the car hits a bump in the road, it oscillates up and down with a period of 1.70s.
Only two forces act on an object (mass = 4.60 kg). (F = 68.0 N.) Determine the magnitude and direction (relative to the x axis) of the acceleration of the object.
A particular guitar string is supposed to vibrate at 200Hz, but it is measured to actually vibrate at 209Hz. By what percent should the tension in the string be changed to get frequency to the correct value.
An electron starts from rest 5.00 cm from the center of a uniformly charged sphere of radius 4.00 cm. If the sphere carries a total charge of 1.00 x10-9 C, how fast would the electron be moving when it reaches the surface of the sphere.
What is the speed of the arrow as it leaves the bow. At a height of 5 meters above the surface of a lake, a sound pulse is generated. The echo from the bottom of the lake returns to point of origin 0.130 s later. The air and water temperatures are ..
