The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.
Problem
Engineers analyzing the motion of a linkage determine that the velocity of an attachment point is given by v = A + 4s2 ft/s, where A is a constant. When s = 2 ft, the acceleration of the point is measured and determined to be a = 320 ft/s2. What is the velocity of the point when s = 2 ft?
