Question
Starting from rest, a race car moves straight up an incline with a 37.0° angle at a constant acceleration for 5.00 s such that its speed reaches 24.0 m/s.
The road becomes horizontal, and the car slows down with constant acceleration as it follows a circular curve that changes its direction by 90°. The radius
of the curve is 122 m, and the car is moving at a speed of 9.00 m/s at the end of the curve.
Assume the ramp is in the xx-plane, and after turning, the car is moving in the y-direction.
(a) Find the total displacement of the race car.
