You want to figure out just how crazy a driver your friend is. As one of many stop lights begins to change green, you produce a small metal ball on a string and let the ball hang down. As usual, your friend floors the accelerator and you note that while the car is accelerating, the ball sweeps back toward the back of the car so that the ball’s string makes an angle of about 35 degrees with the vertical. What is acceleration of the car in both meters per second squared and in terms of g’s (an acceleration equivalent to what multiple of Earth’s gravitational acceleration g)?

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –
