Exercise 3. An elevator is ascending with constant velocity vo = 5 m/s. At 30 m above the ground, the lifting chain cracks and the elevator descends, after a short remaining time of ascending, to the ground. a) At what time does the elevator hit the ground, when the chain cracks at to = Os? b) What is the striking velocity? c) What is the total height of fall?

Please 11 explain me easy way
A baggage handler at an airport applies a constant horizontal force with magnitude F₁ to push a box, of mass M, across a rough horizontal surface with a very small constant acceleration a. ( Figure 1) Figure 2F Submit ▾ Part B Now assume that the baggage handler pushes a third box (Figure 2) of mass m/2 so that it accelerates at a rate of 2a. How does the magnitude of the force F that the handler applies to this box compare to the magnitude of the force F₁ applied to the first box? ▸ View Available Hint(s) 0 2F Submit

- Figure above shows the cross section of a wall made of two layers. The thickness of the 2 nd layer is L2= 0.70L1. The thermal conductivities of the layers are 0.25 and 0.75 W/mK, respectively and thermal conduction is steady. If the temperatures at inlet and between the layers are Ti = 30.0°C and T=8 °C, respectively; what is the outside temperature To for unit area?
