A bicycle wheel has an initial angular velocity of 1.50 rad/s.
a) The new angular velocity will be given by
1.5 + 0.3 * 2.5 = 2.25 rad/s
b) The total number of radians rotated will be the average angular velocity multiplied by the total duration (2.5 seconds).
Since this is a simple constant acceleration, the angular velocity is linear, so we can simply average the start and end points:
average angular velocity = (1.5 + 2.25)/2 = 1.875 rad/s
multiplied by the time interval:
1.875 * 2.5 = 4.6875 radians
dude you forgot to prompt what is the cost of the tangential area of the linear acceleration of a particle is it placed at a distance of 40 5 cm from the axis of rotation while the flywheel bursts at eighty rpm? i hate the cover
