A 47.3-cm diameter disk rotates with a constant angular acceleration of 2.70 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at this time.
(a) Find the angular speed of the wheel at t = 2.30 s. rad/s
(b) Find the linear velocity and tangential acceleration of P at t = 2.30 s. linear velocity m/s tangential acceleration m/s2
(c) Find the position of P (in degrees, with respect to the positive x-axis) at t = 2.30s. °
A flight attendant pulls her 72.0 N flight bag a distance of 282 m along a level airport floor at a constant speed. The force she exerts is 33.0 N at an angle of 52.0° above the horizontal.
Determine the speed of M2 at a time 1.85 s after the system is free from rest.
A meter stick supported at the 50 cm mark has masses of 300 g & 200 g hanging from it at the 10-cm & 60-cm mark, respectively. Where should we hang a third, 400-g mass to keep the meter stick balanced?
A hydrogen molecule with an initial velocity of 1200m / s makes a collision with a molecule of oxygen at rest. The reason for the masses of molecules is mO / mH = 16. What are the speeds of the molecules after collision.
what would the period of the system be. When a particular mass-spring system is started by stretching the spring 5 cm, one complete oscillation takes 2 seconds.
A metal sphere A has charge Q. Two other spheres, B and C, are identical to A except they have zero net charge. A touches B, then the two spheres are separated
Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 3.50 m below the edge. Explain how fast is she going just before she lands?
A motorcycle cop, parked at the side of a highway reading a magazine, is passed by a woman in a red Ferrari 308 GTS doing 90.0 km/h. After a few attempts to get his cycle started, the officer roars off 2.00 s later.
Find the speed of a satellite moving in a circular orbit just above the surface of Mars. Mars has a radius of 3.40 106 m and a mass of 6.42 1023 kg
A typical compact disc stores information in tiny pits on the disc's surface. What's the frequency of electromagnetic waves that have a wavelength equal to the typical CD pit size
Find out the change in entropy of the system
find the work done to move the particle from x = 0 to x = 10.0 m by graphically determining the area under the F versus x graph. (Do this on paper. Your instructor may ask you to turn in this graph.)
