given by A solid sphere is free to rotate about the z axis, as shown. It's angular position as a function of time is e(t)=0.77 rad + (20.61 rad/s/2)+3/2 - (2.58 rad/s5/2) +5/2 33% Part (a) What is the angular position, in radians, at 2.71 s? 33% Part (b) What is the angular velocity, in radians per second, at 3.42 s? Y 33% Part (c) What is the angular acceleration, in radians per squared second, at 6.09 s? a(6.09 s) = rad/s sin() cotan() atan() acotan() cosh() tanh() O Degrees O Radians cos()) asin() tan()) acos() sinh() cotanh() Submit () 7 7 8 9 E M 4 5 6 1 2 3 /* + 0 NO BACKSPACE Hints: 1 for a 0 % deduction.
