What are 26.3 and 57.69?
If the tire of a car, with a radius of 10 in, is rotating at a constant speed, making two entire rotations every second, and runs over a nail that gets fully lodged in the tire, this is how long it will take after running over the nail for its base to first reach a height of 16 in high.
What is 0.176 s?
What is 1882?
