QCA block of mass 3.00 kg is pushed up against a wall by a force P that makes an angle of 0 = 50.0° with the horizontal as shown in Figure P5.12. o The coefficient of static friction be- g tween the block and the wall is 0.250. (a) Determine the possible values for the magnitude of P that allow the block to remain stationary. (b) De- scribe what happens if P| has a larger value and what hap- pens if it is smaller. (c) Repeat parts (a) and (b), assuming

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
