- i need help with this pleaseTwo blocks are connected by a string that goes over an ideal pulley as shown in the figure and pulls on block A parallel to the surface of the plane. Block A has a mass of 3.00 kg and can slide along a rough plane inclined 30.0 degrees to the horizontal. The coefficient of static friction between block A and the plane is 0.400. What mass should block B have in order to start block A sliding up the plane? ANSWER FORMAT: space EXAMPLE: 10.0 N В 30.0°3 Consider shooting a bullet of mass m to three different big blocks. The resistance of the first block is assumed to be proportional to the bullet speed, that for the second block is proportional to vž, and that for the third block is proportional to v². If you fire at these blocks one by one with the same initial speed of vo for your bullets, compute the farthest the bullet can travel in each of these all three cases. Note that the gravitational force for this problem is negligible.
