- A turntable is off and is not spinning. A 0.2 g ant is on the disc and is 5 cm away from the center. The turntable is turned on and 0.6 s later it has an angular speed of 33 rpm. Assume the angular acceleration is constant and determine the following quantities for the ant 0.3 s after the turntable has been turned on. Express all quantities using appropriate mks units. @= V= Enter a number ih units. atan = arad = a = Fnet =I am having trouble with a 3 d motion problem. The problem is as follows, "A point on a rotating turntable 20.0 cm from the center accelerates from rest to a final speed of 0.600 m/s in 1.80 s. At t = 1.29 s, find the magnitude and direction of each of the following." The problem asks me to find the radial acceleration, the tangential acceleration, and the total acceleration of the point. Thanks for the help.T3.14 Please help me answer this physics question.
- You have a horizontal grindstone (a disk) that is 87 kg, has a 0.31 m radius, is turning at 94 rpm (in the positive direction), and you press a steel axe against the edge with a force of 23 N in the radial direction. The kinetic coefficient of friction between steel and stone is 0.20. What is the number of turns, N, that the stone will make before coming to rest?A washing machine needs 17.1 s to speed up from rest to top speed of 5 rotation for every 3.05 s.

- Question 4. A single bead can slide without friction on a vertical hoop of radius r. The hoop rotates about its vertical axis and makes one complete revolution in T seconds. The position of the bead is described by the angle 0. At what 0 > 0 can the bead stay stationary while the hoop rotates? rYou are swinging a 0.45 kg water balloon vertically. The distance from your shoulder (acting as the center of rotation) and the water balloon is about 0.70 m. You estimate the water balloon is traveling at 6.0 m/s. At the very bottom of the circular path, how much force is your hand holding the water balloon?The spin-drier of a washing machine slows down uniformly from 700 rpm (revolutions per minute) to 180 rpm while making 50 revolutions. Find the angular acceleration through these 50 revolutions. Express your answer in rad/s2.
