A car goes around a circular curve on a horizontal road at constant speed. What is the direction of the friction force on the car due to the road? a) tangent to the curve in the forward direction b) tangent to the curve opposite to the direction of the car's motion c) perpendicular to the curve outward d) perpendicular to the curve inward e) There is no friction on the car because its speed is constant

4) The diagrams below show a ball swinging on a string. The diagrams show the ball's position at equal time intervals. The first position is when the ball is moving up and left. Copy these into your lab notebook and then draw acceleration vectors for the ball on each one the acceleration points the way you drew it for each diagram. The arrows show the ball's relative speed and direction at each instant and turnaround points have...

(20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is the acceleration when the car is coming to rest? C) List all known variables with their values. D) What is the acceleration...
