Multiple-Concept Example 8 provides useful background for part b of this problem. A motorcycle, which has an initial linear speed of 6.8 m/s, decelerates to a speed of 2.0 m/s in 5.2 s. Each wheel has a radius of 0.69 m and is rotating in a counterclockwise (positive) direction.
(a) What is the constant angular acceleration? (Indicate direction by the sign of the angular acceleration.)
(b) What is the angular displacement (in rad) of each wheel?
The concrete encloses one steel reinforcing rod with cross-sectional area 1.00cm2. The rod joins two strong end plates. The cross-sectional area of the concrete perpendicular to the rod is 47.5 cm2. Young's modulus for the concrete is 3.00 x 10^10 N/..
