Question

1 out of 4 attempts intermediate steps rounded to four significant figures, Give your final answer(s) to four significant figures wer(s) to four The position of a car as a function of time r, with r > 0 and expressed in seconds, is r (t)-1 (621-130) i, + (1.6 + 31.31-851/2)/1 ft. Determine the slope θ of the trajectory of the car for ti-l s and t2-3 s. In addition, find the angle o between velocity and acceleration for 1 -1 s and 12 -3 s. Based on the values of ф at t1 and t2, argue whether the speed of the car is increasing or decreasing at 1 and t2
