Mechanics

Two bricks P and Q each of mass 5kg, are connected by a ligh inextensible string. Brick P is held at rest and Q hangs freely, vertically below P. A force of 200N is then applied vertically upwasrds to P causiong it to accelerate 1.2 m/s^2. Assuming there is a resistance to the motion of easch brick of magnitude RN find:

a) Value for R

b) Tension


For a why do we ignore the tension when resolving vertically?
