Abo Zeid 10/5/2024  Example 2.5 Average and Instantaneous Acceleration The velocity of a particle moving along the x-axis varies in time according to the expression vx = 40 -5t 2 m /s, where t is in seconds. 46 Physics Prof. Dr. E. F. Abo Zeid 10/5/2024  (b) Determine the acceleration at t = 2.0 s. 47 Physics Prof. Dr. E. F. Abo Zeid 10/5/2024  2.5 One Dimensional Motion with Constant Acceleration 48 When the velocity of an object changes at the same rate throughout the motion the acceleration is said to be constant. Thus, the velocity-time graph becomes a straight line Physics Prof. Dr. E. F.
