What is the magnitude of the third force, F3, so that the acceleration of the object is 0?Two blocks A and B with mA = 0.9 kg and mB = 0.80 kg are connected by a string of negligible mass. They rest on a frictionless horizontal surface. You pull on block A with a horizontal force of 7.8 N. (A) Find the magnitude of the acceleration (in m/s2) of the blocks. (B) Determine the tension (in N) in the string connecting the two blocks.
- When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 965 N and the drag force has a magnitude of 1016 N. The mass of the sky diver is 98.5 kg. Take upward to be the positive direction. What is his acceleration, including sign?Two forces are applied to a block to accelerate it across a horizontal surface. If a = 21.40 , F = 3.89 N, and m = 1.91 kg, find the magnitude of the acceleration a for the block. Assume the surface is frictionless.A particle is being pulled by two forces: F1 = 3.0 N, East and F2= 4.0 N, West. Find the resultant force acting on an object.
