A block with mass m1 (which we call block 1) is pulled by a rope with tension T along the ground as shown in the figure where the coefficient of kinetic friction between the ground and the block is . On top of this block is another block of mass m2 (block 2) which is moving in the same direction as m1 but sliding relative to m1 in the opposite direction ( x –axis ). The coefficient of kinetic friction between the two blocks is . a) Which of the following can be the free body diagram for block 2? (5 pts.) 1) 2) 3) 4) b) What is the acceleration of block 2 in the horizontal direction ( x – axis )?

Turning back to high school math can be essential to understand engineering tasks that you may encounter later. The high school math problems have all the basics that have good equations and answers, which will let you see things clearly. The list of high school math questions below will help you identify your weaknesses and find various solutions. Taking a look at high school math equations, you will see certain parts that can be applied to Physics. In either case, the best way is to learn by example, which is why high school math problems with answers will be essential.
