Question:
In each of the following cases t ≥ 0. The quantities are given in SI units, so distances are in metres and times in seconds.:
i. Find expressions for the velocity and acceleration at time t
ii. Use these expressions to find the initial position, velocity and acceleration
iii. Find the time and position when the velocity is zero.
a. s = 5t² – t + 3
b. s = 3t – t³
c. s = t4 – 4t – 6
d. s = 4t³ – 3t + 5
e. s = 5 – 2t² + t
