- Given:wheel, radius = 16 cmspins with angular speed 75 rev/min.Find tangential velocity of a rock on the edge of the wheel.Refer to the picture below.Imagine that you could see a wheel spinning while speeding up, so you know that the angular velocity is (answer choice 1) , and the angular acceleration is (answer choice 2). But if instead the wheel is spinning counter clockwise and slowing down, so you know that the angular velocity is (answer choice 3) , and the angular acceleration is (answer choice 4). answer choices: out of page (positive) or into page (negative)
