If the bug has a mass of 0.05 kg and accelerates at 2 m/s2 whats the net force on the bug

What happens in a global convection cell

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?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
