A coin is placed 18.0 cm from the axis of a rotating turntable
of variable speed. When the speed of the turntable is slowly
increased, the coin remains fixed on the turntable until a rate of
35.0 rp (revolutions per minute) is reached, at which point the
coin slides off.
Part A- What is the coefficient of static friction between the
coin and the turntable? Express your answer using three significant
figures.

A cylinder 100 mm in diameter and 80 mm long with an initial
temperature of 527 C is suddenly exposed to water at 27 C giving a
convective heat transfer coefficient of 400 W/m2-K. Determine the

density is 8050 kg/m3, specific heat is 536 kJ/kg-K, and thermal
conductivity is 18.6 W/m-K.

A wheel is rotating about an axis that is in the z-direction.
The angular velocity ωz is -6.00 rad/s at t = 0, increases linearly
with time, and is +4.00 rad/s at t = 19.0 s . We have taken
counterclockwise rotation to be positive.
How long is the time interval during which the speed of the
wheel is increasing?
