The figure here shows an overhead view of three horizontal forces acting on a cargo canister that was initially stationary but that now moves across a frictionless floor. The force magnitudes are F₁ = 2.80 N, F₂ = 3.60 N, and F3 = 10.0 N, and the indicated angles are 0₂ = 52.0° and 03 = 32.0°. What is the net work done on the canister by the three forces during the first 4.00 m of displacement? 8₂ 0₂

The spring-flex exercise system consists of a spring with one end fixed and a handle on the other end. The idea is that you exercise your muscles by stretching the spring from its natural length, which is 48 cm. If a 200 Newton force is required to keep the spring stretched to a length of 66 cm, how much work is required to stretch it from 62 cm to 76 cm? Your answer must include the correct units. Work=

The figure shows three forces applied to a trunk that moves leftward by 3.23 m over a frictionless floor. The force magnitudes are F1 = 4.70 N, F2 = 8.63 N, and F3 = 3.16 N, and the indicated angle is 0 = 60°. (a) During the displacement, what is the net work done on the trunk by the three applied forces, the gravitational force, and the normal force? (b) Is there a net transfer of energy to or from the trunk? (c) Does the kinetic energy of the trunk increase or decrease? (a) Number i Units (b) (c) >
