No Chatgpt please 6. A lever system can allow us to lift heavy objects with less force. Consider one lever to lifta 1000-kg mass as drawn below. The lever is a large uniform steel beam with mass of120 kg and a moment of inertia of 251 kgm² about the fixed pivot point.0.45 m0.25 m1000 kg2.70 mFappIn this horizontal position, what applied force on the other end is needed to acceleratethe 1000-kg mass upward at 1.0 m/s²? (Hint: Due to the acceleration, the tension of thehanging mass is not simply (1000kg)g. Also, the angular acceleration of the beam is not0.)Bonus: Even though you are using substantially less force to lift the 1000-kg mass,explain how energy is still conserved.

Objects A and B are both blocks, and they slide down their respective ramps without rotating. Object C rolls down the ramp without slipping. Its moment of inertia is unknown. All three objects are released from resti old lots B Objects A, B, and C are made of different materials, thus the coefficients of friction between the objects and their corresponding ramps are not necessarily the same. m = m, = mc Object A reaches the bottom of its ramp first, followed by objects B and C, which reach the bottom at the same instant. Rank the center-of-mass accelerations of objects A–C according to magnitude, from largest to smallest. If any objects have the same magnitude center-of-mass acceleration, state so explicitly.
