Suppose a wheel with a tire mounted on it is rotating at the constant rate of 3.33 times a second. A tack is stuck in the tire at a distance of 0.309 m from the rotation axis. Noting that for every rotation the tack travels one circumference, find the tack's tangential speed

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
