As shown in Figure Q3 the collar starts from rest at 1. Using hand calculations: (i) Find the collar's speed at 2. (ii) Find the minimal force P for which the collar will reach 2. P = 20 N (in Part (i)); m (collar) = 1.8 kg Using MATLAB: Plot the variation of the collar's speed with the distance L. 2,5m Smooth rod and constant force P g L₁ 30° L₂ 2m Figure Q3 P h = 1m As shown in Figure Q3 the collar starts from rest at 1.
