A turntable A is built into a stage for use in a theatrical production, see Fig Q2. It is observedduring a rehearsal that a trunk B starts to slide on the turntable 10s after the turntable beginsto rotate. Knowing that the trunk undergoes a constant acceleration of 0.24m/s2, determine thecoefficient of static friction between the trunk and the turntable.

You place a penny on a turntable at a distance of 11.6 cm from the center. The coefficient of static friction between the penny and the turntable is 0.380. The turntable's angular acceleration is 2.25 rad/s22. How long after you turn on the turntable will the penny begin to slide off of the turntable?

A 88.6 g drink is left on a turntable causing it to turn with an angular speed of 8.80 rad/s. If the drink has coefficients of friction of μs = 0.970 and μk = 0.470 with the turntable, what is the furthest distance that the drink could have been placed from the centre of the turntable for the drink not to slide? 0.0125 m 0.0595 m 0.00135 m 0.123 m

fixed position and cannot move left, right up or down. Object 1 is being accelerated5. 41 𝑚/𝑠2. What is the friction coefficient of Object 1 and table top? Assume𝑔 = 9. 8 𝑚/𝑠2 and let us agree that moving to the left is the positive direction ofobject 1.

Hence calculate the coefficient of friction for this situation.

A bug crawls around on a horizontal turntable rotating with constant angular speed ω. The massof the bug is m and the coefficient of friction of the bug with the surface of the turntable is µ.Recall that Fstatic friction ≤ |µN | where N = mg is the normal force. The onset of slippage occurswhen Fstatic friction = |µN |. Gravity points downward. Ignore non-inertial effects due to Earth’srotation.a) The bug crawls with constant speed vr relative to the turntable in a radial path. How farfrom the center of the turntable can the bug crawl before starting to slip (in terms of ω, µ,and g)?b) The bug crawls with constant speed vr relative to the turntable in a circular path of radius bon the turntable. The circular path is concentric with the center of the turntable. For whatvalue of vr (in terms of ω, b, µ and g) will the bug start to slip if it crawlsi) In the direction of rotation?ii) Opposite of the direction of rotation?
