I need help on this problem
![7. The position of a car moving along a flat surface at time t is modeled by (x(t), y(t)) with velocity
vector v(t) = (3+6 sin(3t), 1+ e2") for 0 <t < 2. Both r(t) and y(t) are measured in feet, and t is
measured in seconds. At time t = 0, the car is at position (0,0).
(a) Find the position of the car at time t = 2.
(b) At what time t, for 0 <t < 2, is the line tangent to the path of the car parallel to the y-axis?
(c) Write, but do not evaluate, an integral expression that gives the total distance traveled by the
car from time t = 0 to time t = 2.
(d) Write, but do not evaluate, an integral expression that gives the average speed of the car from
time t = 0 to time t = 2.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F62cc3b2c-ca5c-4dc2-884f-aa56aeff03f7%2Fd904ab27-3327-4043-a630-2a7a3c908fe7%2F47h5tw_processed.png&w=3840&q=75)
