28. (a) A red car travelling at a speed of 40 km h to north, then turns to west without
changing its speed. Does the car experience acceleration? [1 m]

(b) The car continues to travel at a speed of 72 km h when it reaches the highway.
Suddenly the driver steps on the brake when he saw a fallen tree on the road at

60.0 m in front of him. The car experiences a deceleration of 5 m s . Will the car
stop before it hits the tree? [3 m]
