The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.

Problem

The angular acceleration of the line L relative to the line L0 is given as a function of time by α = 2.5 – 1.2t rad/s2. At t = 0. θ = 0 and the angular velocity of L relative to L0 is ω = 5 rad/s. Determine θ and ω at t = 3 s.
