Question
A wheel of radius r = 43.1 cm and rotational inertia about the axis of 0.09 kg.m? fixed on a frictionless inclined
plane that makes angle = 29° with the horizontal. An m = 1.6 kg block is held on the plane by a massless string
wrapped around the wheel. A force of magnitude F = 7.2 N is applied to the block in the direction shown in the
!!
figure below. Calculate the magnitude and direction of the angular acceleration of the wheel?
[Recommended time : 5-8 minutes]
O a. 8.0 rad/s^2 Direction: Clockwise
O b. 16.5 rad/s^2 Direction: Clockwise
O C. -0.4 rad/s^2 Direction: Counter-clockwise
O d. 0.4 rad/s^2 Direction: Clockwise
O e. B.O rad/s^2 Direction: Counter-clockwise
O f. 16.5 rad/s 2 Direction: Counter-clockwise
