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?

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
