Question

An object moves along the x axis according to theequation x(t) = (4.00t² - 2.00t+ 3.00) m, where t is in seconds.

(a) Determine the average speed betweent = 3.50 s andt = 5.40 s.
m/s
(b) Determine the instantaneous speed at t = 3.50 s and at t = 5.40 s.
m/s (t = 3.50)
m/s (t = 5.40)
(c) Determine the average acceleration between t =3.50 s and t =5.40 s.
m/s²
(d) Determine the instantaneous acceleration at t =3.50 s and t =5.40 s.
m/s² (t = 3.50)
m/s² (t = 5.40)
