Transcribed Image Text:2. The position of a particle between t = 0 and t = 2.00s is given by a(t) = (3.00 m/s³)³-(10.0 m/s²)t² + (9.00 m/s)t.
a) Find expressions for
(i) the particle's velocity as a function of time (v (t)), and
(ii) the particle's acceleration as a function of time (a (t)).
b) Sketch
(i) an a vs. t graph for this particle,
(ii) a v vs. t graph for this particle,
(iii) an a, vs. t graph for this particle.
(For this part, you may use a graphing calculator or computer; curve-sketching techniques you may have
learned in math can also be helpful, and will be illuminating when answering some of the later parts of the
question.)
