A63-kg canoeist stands in the middle of her 39-kg canoe. initially, both the canoeist and the canoe are at rest, and the canoe is pointing directly toward the shore. what is the speed of the canoe relative to the shore?

Derive the formula 2as=v² -u² where the formula have have usual meanings

Idon’t know the answer to it and am stuck.

Two wooden members of 80 × 120-mm uniform rectangular cross section are joined by the simple glued scarf splice shown. knowing that β = 22° and that the maximum allowable stresses in the joint are, respectively, 400 kpa in tension (perpendicular to the splice) and 690 kpa in shear (parallel to the splice), determine the largest centric load p that can be applied using mohr's circle. (round the final answer to two decimal places.)
