A 34cm diameter wheel accelerates uniformly about its center from 130rpm to 370rpm in 4.8s . Determine the radial component of the linear acceleration of a point on the edge of the wheel 1.6s after it has started accelerating. Determine the tangential component of the linear acceleration of a point on the edge of the wheel 1.6s after it has started accelerating.
A certain engine can exert 75,000 kg m/sec/sec of force. Assuming that all the force is used to accelerate the vehicle on which the engine is mounted, how fast would the vehicle accelerate assuming that it masses 5,000 kg? Neglect friction/air res..
Two wheels have the same mass and radius of 4.5 kg and 0.39 m, respectively. One has (a) the shape of a hoop and the other (b) the shape of a solid disk. The wheels start from rest and have a constant angular acceleration with respect to a rotatio..
