ANY HELP WOULD BE APPRECIATED, THANKS
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
Assume the three blocks portrayed in Figure P4.59 move on a frictionless surface and a 42-N force acts as shown on the 3.0-kg block. Determine (a) the acceleration given this system, (b) the tension in the cord connecting the 3.0-kg and the 1.0-kg blocks, and (c) the force exerted by the 1.0-kg block on the 2.0-kg block. 42 N 3.0 kg 1.0 kg 2.0 kg Figure P4.59
(2) The box with M = 40kg shown below is being pulled by two pulleys exerting forces F₁ = 400 N (0₁ = 60°) and F₂ = 200 N (0₂= 15°) up an incline with an angle 0₁ = 30°. If the uk = 0.15. What is the acceleration of the box? Would the F₁ or F₂ be enough alone to pull the box up if the other pulley would stop working?
Question 4
Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
