Suppose the position vector for a particle is given as a function of time by r(t) = x(t)i + y(t)i, with x(t) = at + b and y(t) = ct + d, where a = 1.10 m/s, b = 1.40 m, c = 0.123 m/s, and d = 1.14 m.

Suppose the position vector for a particle is given as a function of time by r(t) = x(t)i + y(t)i, with x(t) = at + b and y(t) = ct + d, where a = 1.10 m/s, b = 1.40 m,
c = 0.123 m/s?, and d = 1.14 m.
(a) Calculate the average velocity during the time interval from t = 1.90 s to t = 3.95 s.
v =
m/s
(b) Determine the velocity at t = 1.90 s.
v =
m/s

A fish swimming in a horizontal plane has velocity v, = (4.00 i + 1.00 j) m/s at a point in the ocean where the position relative to a certain rock is ř = (16.0 i - 3.00 J) m.
After the fish swims with constant acceleration for 17.0 s, its velocity is v = (21.0 î - 3.00 j) m/s.
