An object slides on a flat, frictionless surface. At t=0 s, it is at position 2; = -1.0 m, with a velocity V; = 1.3 m/s, subject to an acceleration a, = ? m/s?. At t= 3.3 s, the object's velocity is Ur =? m/s and its position is -4.8 m. Find the object's acceleration a, (in m/s-). The system will not recognize units, or scientific notation. Round your answer to twi decimal places at the end of your calculations
