![The position of a car as a function of time t, with t > 0 and expressed in seconds, is
7 (1) = [ (621 118) + (1 +31.5t - 8.77²)5] ft.
Determine the slope of the trajectory of the car for t₁ = 1 s and f₁ = 3 s. In addition, find
the angle between velocity and acceleration for t1 = 1 s and 72 − 3 s. Based on the values of
o at t₁ and f. argue whether the speed of the car is increasing or decreasing at 1 and 2.
