1 An airplane travels east at a velocity of 250 m/s and at the same time is blown north with a velocity of 50 m/s.
Draw a vector diagram of the velocities, including the resultant velocity of the
airplane.
You should include labels and axes values on your diagram.

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

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?

This is the number of complete movements of a wave per second.
