A large grinding wheel in the shape of a solid cylinder of radius 0.330 m is free to rotate on a frictionless, vertical axle. A constant tangential force of 250 N applied to its edge causes the wheel to have an angular acceleration of 0.940 rad/s2.
(a) What is the moment of inertia of the wheel?
(b) What is the mass of the wheel?
(c) If the wheel starts from rest, what is its angular velocity after 5.00 sec have elapsed, assuming the force is acting during that time.
Consider the motion of a muon as it moves through the Earth's atmosphere. After a time ? = 2.20 multiply.gif 10-6 s, What is the speed of the muon
Small particles suspended in the air have a v_rms = 2.8 x 10^-3m/s. What is the mass of one of the small particles

ball rolls horizontally off the edge of a tabletop that is 1.80 m high. It strikes the floor at a point 1.32 m horizontally away from the table edge. (Neglect air resistance.) (a) How long was the ball in the air? s (b) What was its speed at the i..
The total electric field consists of the vector sum of two parts, Find the magnitude and direction of the total field, Specify the directional angle relative to the x axis
A ball is thrown toward a cliff of height (h) with a speed of30 m/s and an angle of 60 degrees above the horizontal. What is the ball's impact speed
Two identical spacecraft are to be accelerated by rockets. The first rocket fires with a force 4 times as large as that of the second rocket. The acceleration of the first rocket is how many times as vast as the acceleration of the second rocket.
A sled is pulled with a horizontal force of 20 N along a level trail, and the acceleration is found to be 0.35 m/s2. An extra mass m = 4.2 kg is placed on the sled. If the same force is just barely able to keep the sled moving, what is the coeffic..
Shaving/makeup mirrors typically have one flat and one concave (magnifying) surface. compute the focal length of the mirror
If a mass of 1 kg is accelerated 1 m/s2 by a force of 1 N, illustrate what would be the acceleration of 10 kg acted on by a force of 20 N?
A meterstick (L = 1 m) has a mass of m = 0.121 kg. Initially it hangs from two short strings: one at the 25 cm mark and one at the 75 cm mark. What is the tension in the left string?
A spacecraft is traveling with a velocity of vox = 5675 m/salong the +x direction. Two engines are turned on for a time of 847 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.25 m/s2,while the other gives it an acc..
