Kindly plss answer thiss question The acceleration of a particle is given by a = 7t - 32, where a is in meters per second squared and t is in seconds. Determine the velocityand displacement as functions of time. The initial displacement at t = 0 is so = 2 m, and the initial velocity is vo = -8 m/s. After you havethe general expressions, evaluate these expressions at the indicated times.Answers:At t = 3.5 s, S=Att = 8.9 s, S =m, V = i3m,V =m/sm/s
