[b]1. There is a 45 kg block that is connected to a 30 kg block by a mass-less rope. The surface is frictionless. A force of F=200 N pulls the blocks to the right and in the positive direction. What is the magnitude of the tension T in the rope that connects the two blocks?
[b]2. I am not...
[b]1. What is the acceleration of the 20 kg block if the block is being pulled with a force of 150 N at 60 degrees above the X+ axis and there is a frictional force of 20 N acting on the block?
[b]2. F=ma, Fcos(theta).
[b]3. I did (150)cos(60)=(20)a ---> 75=20a ---> a=3.75 m/s...
