A truck accelerates uniformly from rest and after 5 seconds the 50−cm radius wheels on the truck have an angular velocity ωf = 47 rad/s. (a) What is the magnitude of the angular acceleration, α, of the wheels? α = rad/s2 (± 0.1 rad/s2) (b) What is the magnitude of the final velocity, vf, of the truck? vf = m/s (± 0.1 m/s) (c) Through what total angle does each wheel turn in this time? θ = rad( ± 1 rad)
