A bicycle wheel has an initial angular velocity of 1.50 rad/s.

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/sec
b) The total number of radians turned will be the average angular velocity multiplied by the total duration (2.5 seconds).
Since this is simple constant acceleration, the angular velocity is linear, so we can just take the average of the starting and stopping points:
average angular velocity = (1.5 + 2.25)/2 = 1.875 rad/sec
multiplied by the time interval:
1.875 * 2.5 = 4.6875 radians

dude you forgot to invite what’s the cost of the tangential area of the linear acceleration of a particle it is placed at a distance of 40 5 cm from the axis of rotation whilst the flywheel is popping at eighty rev/min? I hate capa
