- Please AsapYou have a horizontal grindstone (a disk) that is 88 kg, has a 0.31 m radius, is turning at 89 rpm (in the positive direction), and you press a steel axe against the edge with a force of 17 N in the radial direction. Assuming that the kinetic coefficient of friction between steel and stone is 0.20, calculate the angular acceleration of the grindstone in rad/s2. What is the number of turns, N, that the stone will make before coming to rest?For rolling without slip, the acceration of a circular disk on an incline plane a=r(alpha) where alpha = to the angular accleration. Qn. What is the difference in acceleration with slipping vs without slipping? Also, why is there no centripetal acceleration (towards the centroid of disk) when the disk is rolling without slippage?
- please help!A circular object rotates with an angular velocity ω=4.2t2 + 3.0. (Take [ω] = radians/second ). A. Find an expression for the angular acceleration ?(t). B. Calculate ?(t = 3 s). C. Calculate Δθ between 0 s and 3 s. Hint: See examples in Section 10.1 in the text.A ball rolling down a ramp accelerates steadily from 1.5 rad/s to 5.5 rad/s at an angular acceleration of .50 rad/s^2. What total angular distance does it travel in this time? ____ rad (two significant figures- round to the ones place)
- Please solve and answer the question correctly. Thank you!!Pls.help.The angular position of a rotating object as a function of time is given below: e = 3.113-2.5t2 +4.7t+d Here e is in units of radians and t is in units of seconds and d is constant. Determine the instantaneous angular acceleration of the object at t=2.9s. Express your answer in units of rad/s using one decimal place.
- A disk spins at 4.0 revolutions/second. What is its period, in second? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.A rock tied to the end of the string swings at a constant angular rate. If you are told that the string can support a total of 100 N of force before breaking, what is the maximum angular velocity the rock can rotate if the rock has a mass of 0.2 kg, and the length of the string is 0.5m?
