The acceleration of a particle traveling along a straight line is a = ¼ s1/2 m/s2 ,where s is in meters. If v = 0 m/s and s = 1 m when t = 0 s, determine the particle’s velocity at s =2 m.NOTE #1 – A sketch of the scenario should be created by you to enhance your work.NOTE #2 – A particle is rather uninspiring, yet they are suitable in learning engineering scienceprinciples. You are welcome to spice up this problem by replacing the particle with a rigid bodyof interest to you. You are welcome to comment on your answer how replacing abstract conceptswith tangible examples influences your learning of dynamics topics
