An object is moving along the x-axis and its position varies in time according to the expression x = (3.00 m/s²)t², where x is in meters and t is in seconds. (a) Determine its position (in m) at t = 4.00 s. (b) Determine its position (in m) at t = (4.00 s) + At. (Use the following as necessary: At. Do not include units in your answer.) (c) Evaluate the limit of. as At approaches zero to find the velocity (in m/s) at t = 4.00 s.
