Two blocks of mass m1 and m2 > m1 are drawn above. The block m1 sits on a frictionless inclined plane tipped at an angle θ with the horizontal as shown. Block m2 is connected to mı by a massless unstretchable string that runs over a massless, frictionless pulley to hang over a considerable drop. At time t = 0 the system is released from rest. a) Draw a force/free body diagram for the two masses. b) Find the magnitude of the...

Two masses are being pulled up a 30.0 degree incline by a force F parallel to the incline. The acceleration down the incline is 1.00 m/s2 and the velocity is up the incline. The force is applied to a 200 kg mass, and a string connects the 200 kg mass to a 150 kg mass. The coefficient of kinetic friction is 0.200. What is the tension in the string? answer: 840 N
(a) A force F is applied to a block of mass m1 causing it to be accelerated at 1.9 m/s2. The same force is also applied to another block, m2, which is accelerated at 3.4 m/s2. Find the ratio of m1/m2 (b) The two blocks from the previous problem are combined to make a block of mass m1 + m2. It is being pushed by the same force F from the previous problem. Find the acceleration of the block. __________...
