Question
Given that the position of a particle is defined in terms of time by the equation below, where x is in
meters and t is in seconds, determine:
4t3 + t² 3t2
+
+ 4
t
(a) the average velocity of the particle from t = 1.0 s to t = 3.0 s, (Ans: vave = 16 m/s)
(b) the instantaneous velocity of the particle at t = 2.5 s, (Ans: vx =
20.52 m/s)
(c) the average acceleration of the particle from t = 2.0 s to t = 3.0 s, and (Ans: aave = 8.42 m/s2)
(d) the t at which the instantaneous acceleration of the particle is 8.10 m/s2. (Ans: t = 3.91 s)
