Two blocks are connected by a light string and accelerated upwards by a pulling

Question

Two blocks are connected by a light string and accelerated upwards by a pulling force F. The mass of the upper block is 50.0kg and that of the lower is 100.0kg. The upward acceleration of the system as a whole is 1.50 m/s^2 . neglect the mass of the string. A. Draw the free body diagram for each block. then use the diagrams to determine which of the following is true for the magnitude of the tension in string compared to other forces? B. Apply Newton's laws to find the required pull , F. C. Find the tension, T in the string

Explanation / Answer

Force = (ma) = (50 + 100)/ (1.5 + 9.8) = 1,695N. You're using 10 as g, aren't you! Then the answer is 1,725N. Further, you are rounding it to 1,700N., which is 1.7 x 10^3. You must add g to the system, as it is being pulled up against gravity. This would not be the case if the pull was horizontal.
