Suppose the position vector for a particle is given as a function of time by
r
(t) = x(t)î + y(t)ĵ, with x(t) = at + b and y(t) = ct2 + d, where a = 2.00 m/s, b = 1.40 m, c = 0.129 m/s2, and d = 1.12 m.
(a) Calculate the average velocity during the time interval from t = 2.20 s to t = 4.05 s.
v
= m/s
(b) Determine the velocity at t = 2.20 s.
v
= m/s
Determine the speed at t = 2.20 s.
