In lab, you attach one end of an ideal spring (of negligible mass) to a wall and the other end of the spring to a 0.200kg pascar that sits at rest on a frictionless, horizontal track. you then pull the pascar horizontally and let go, causing it start it oscillating. the elapsed time from when the pascar first moves through the equilibrium point to the second time it moves through the equilibrium point is 2.60s. find the spring constant, k, of the spring.

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?

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?
