The girder increases its speed from 0.25 m/s to 0.75 m/s in a distance of 3.5 m. a. How much work is done by gravity? b. How much work is done by tension?

스크린샷 2022-03-30 오후 12.01.27 An external force F moves a 2.50-kg box at a constant speed v up a frictionless ramp, as shown in the figure. The force acts in a direction parallel to the ramp. 5.00 m -03. Calculate the work W done on the box by this force as it is pushed up the 5.00-m ramp to a height h = 3.00 m. 十 스크 -03. W = 스크로 -0. How does the work done on the box compare to the change in gravitational potential energy AU, that the grav box undergoes as it rises to its final height? O W > AUgrav W < AU grav O W = AU grav
