Question

The x and y coordinates of a tourist (in meters) as a function of time t are given by the following equations:

x(t) = 2.10t² + 3.30t +10.0

y(t) = 2.50t² - 7.70t +20.0

a) Find the coordinates of the tourist in the form of (x,y) at times t = 1.0 s and t = 3.5 s

b) Use your answer in part (a) to determine the tourrist's desplacement beween t = 1.0s and t = 3.5s

c) Use your answer in part (b) to detrmine the tourist's average velocity between  t = 1.0s and t = 3.5s

d) Determine the velocity of the tourisst at t = 3.0s

e) Use your answer in part (d) to detrmine the madnitude and angle of the velocity of the tourist at t = 3.0s

f) At any given point of time, is the acceleration of the tourist increasing, decreasing, or constant?
