QUESTION 1
A light inelastic string connects two blocks of mass 1,5 kg and 2 kg respectively. A force is applied at angle of 20° on block A.
If a force F of 8,25 N is applied on block A, the blocks move at a CONSTANT VELOCITY on the rough surface.
1.1 Calculate the horizontal component of the applied force F.
1.2 Calculate the vertical component of the applied force F.
1.3 Calculate the coefficient of kinetic friction between the blocks and the rough surface.
1.4 How will the frictional force on block A change if the angle of the force changes to 15°? Write down INCREASES, DECREASES or REMAINS THE SAME.
