- A particle moving along a straight line is subjected to a deceleration a=-4v m/s2, where v is in m/a. If it has a velocity v= 10 m/s when t=0, determine its velocity.The acceleration of a particle is given by a = 3t - 32, where a is in meters per second squared and t is in seconds. Determine the velocity and displacement as functions of time. The initial displacement at t = 0 is so = -4 m, and the initial velocity is vo= 7 m/s. After you have the general expressions, evaluate these expressions at the indicated times.
