A particle starts from xi = 10 m at t0 = 0 and moves with the velocity graph shown in the graph below.

Sorry for no graph it's at 12 m/s when time is zero. Moves down consistently so that it is 8 at 1 4 at 2 0 at 3 and negative 2 at 4.

(a) What is the object's position at t = 2 s, 3 s, and 4 s?

m (at t = 2 s)

m (at t = 3 s)

m (at t = 4 s)

(b) Does this particle have a turning point? If so, at what time?

s
