(a) From v ( t ) = 0 we find it is (momentarily) at rest at t = 0. (b) We obtain x (0) = 4.0 m (c) and (d) Requiring x ( t ) = 0 in the expression x ( t ) = 4.0 – 6.0 t 2 leads to t = ± 0.82 s for the times when the particle can be found passing through the origin. (e) We show both the asked-for graph (on the left) as well as the “shifted” graph which is relevant to part (f). In both cases, the time axis is given by –3 t 3 (SI units understood). (f) We arrived at the graph on the right (shown above) by adding 20
