A2.0-kilogram laboratory cart is sliding across a horizontal frictionless surface at a constant velocity of 4.0 meters per second east. what will be the cart's velocity after a 6.0-newton westward force acts on it for 2.0 seconds and in what direction?

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.)
