Abox is moving along the x-axis and its position varies in time according to the expression:
x = (6.00 m/s^2)t^2,
where x is in meters and t is in seconds.
(a) determine its position (in m) at t = 3.20 s.
(b) determine its position (in m) at t = (3.20 s) + δt.
(c) evaluate the limit of δx δt as δt approaches zero to find the velocity (in m/s) at t = 3.20 s.
