Show your work for each part of the question. 2 O O (12 points, suggested time 25 minutes) A crane and box are both initially at rest. At time t = 0 s, the crane begins to drive forward at a constant speed of 0.5 -, while also lifting the box with an upward acceleration of 1 2. The box does not swing while being lifted by the crane (a) On the dot below, which represents the box, draw and label the forces (not components) that are exerted on the box during the scenario described above. Represent each force by a distinct arrow starting O on, and pointing away from, the dot. Note: Draw the relative lengths of all vectors to reflect the relative magnitudes of all the forces.Sign FIFA |ml B40 The How Run M Just FIU Cha FIU Sex FIU Onli :My 6.
