A block 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 = 2.10 s. (b) Determine its position (in m) at t = (2.10 s) + Δt. (Use the following as necessary: Δt. Do not include units in your answer.) (c) Evaluate the limit of as Δt approaches zero to find the velocity (in m/s) at t = 2.10 s.
