- Please help a car travelling North turns and then goes west. What direction was the ac= 4bdd655af6baf8ca630f9c91581eb955.pdf 2 1 2 2/2 Expo Fultsche 3. Speed Limits on Highway and Road Curves Scenario: Imagine a car travelling along a highway at 100 km/h [East] on a cold winter day. The car approaches an off ramp so the driver can turn south off the highway but as the car enters the curve it hits a patch of ice. i) Describe the initial motion of the car. ii) If the car begins to skid when it hits the ice, describe the motion of the car as the driver attempts to enter the curve. The faster the car is going initially, the greater the force required to get it to turn from its initial direction to a new direction. iii) Explain why highway designers usually post signs similar to the one below on tight curves and on/off ramps on roads and highways. 65 ↓
