A wheel 1.75 m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4.05 rad/s2. The wheel starts at rest at t = 0, and the radius vector of a certain point P on the rim makes an angle of 57.3 with the horizontal at this time. At t = 2.00 s, find the following. (a) the angular speed of the wheel 8.1 rad/s (b) the tangential speed of the point P 7.09 m/s (c) the total acceleration of the point P 59.5 magnitude Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s direction 3.4 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. with respect to the radius to point P (d) the angular position of the point P 8.1 Your response differs from the correct answer by more than 100%. rad A wheel 1.75 m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4.05 rad/s2.
