1-D Particle Kinematics – 1-D motion with constant acceleration Initial kinematic quantities at the starting time: Initial position x 0 and initial velocity υ 0 . – Constant acceleration motion 0 2 00 22 1 2 2( ) at x x t at ax x υυ υ = + = ++ = +− – Constant velocity motion 0 0 xx t = = + Example 1. A particle is moving along a straight line with constant acceleration. Measured from a chosen reference frame, the particle‘s starting position is +2 m at t = 0. The particle is observed to move to the origin with a velocity of 0.8 m/s when t = 10 s. Find the time instant when the particle change its direction of motion. ( Ans :6 s) 2. Free fall : A ball is thrown upward at the corner of a building as shown. It takes 5 s for the ball to hit the ground. Find the maximum height of the ball h above the starting point.
