I'm new to the physics course, and these examples are in my text book, but the answers are not given, I'm pretty lost!
An object moves along the x-axis according to x(t) = (300t² - 2.00t + 3.00)m
Determine:
(a) the average speed between t =2.00 s and t = 3.00 s,
(b) the instantaneous speed at t = 2.00 s and t = 3.00 s,
(c) the average acceleration between t = 2.00 s and t = 3.00 s
(d) the instantaneous acceleration at t = 2.00 s
and t = 3.00 s.
Thanks in advance!
