Question

On a flat surface, a car is turning in a circle of radius 40meters at a speed of 20 km/h. The force acting on the car that isdirected towards the center of the circle is: 1- A gravitational force. 2 - A normal force. 3 - A friction force. 4 - A tension force. 5 - An acceleration force. 6 - None of the above. Explain your answer: On a flat surface, a car is turning in a circle of radius 40meters at a speed of 20 km/h.

Explain your answer:

Explanation / Answer

a net force causing a centripetalaccleration actstoward the center of the circular path and effects a change in thedirection of the velocity vector. if that force should vanish theobject would immedietly leave its circular path and move along thestraight line tangent to the circle at the point where the forcevanished. so 5 is correct answer.
