Reference no: EM13667901

A computer disk is 8.0 centimeter in diameter. A reference dot on the edge of the disk is initially located at θ=45 degree. The disk accelerates steadily for 0.50 second, reaching 2000 rpm, and then coasts at steady angular velocity for another 0.50 second.

a) Find the tangential acceleration of the reference dot at t = 0.25 sec?

b) Find the centripetal acceleration of the reference dot at t = 0.25 sec?

c) Find the angular position of the reference dot at t = 1.0 sec?

d) Find the speed of the reference dot at t = 1.0 sec?
