A10 n board of uniform density is 5 meters long. it is supported on the left by a string bearing a 3 n upward force. in order to prevent the string from breaking, a person must place an upward force of 7 n at a position along the bottom surface of the board. at what distance from its left edge would they need to place this force in order for the board to be in static equilibrium?

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?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
