An object of mass m = 1.0 kg is observed to have an acceleration a with a magnitude of 10.0 m/s2 in the direction 60.0O east of north. The force F2 acting on the object has a magnitude of 5.0 N and is directed north. Determine the magnitude and direction of the one other horizontal force F1 acting on the object.

Two forces FA and FB are applied to an object whose mass is 7.20 kg. The larger force is FÁ .When both forces point due east, the object's acceleration has a magnitude of 0.453 m/s?. However, when FA points due east and Fg points due west, the acceleration is 0.337 m/s?, due east. Find (a) the magnitude of FA and (b) the magnitude of FB. (a) Number i Units (b) Number i Units

Block 1 (10 kg) is pulled by a rope from left to right up a ramp which is inclined 50 degrees from the horizontal. The rope pulls on block 1 with a force of 150 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.3. Weight force on block 1 by EarthW1E = Tension force on block 1 by RopeT1R = Normal force on block 1 by SurfaceN1S = Frictional force on block 1 by Surfacef1S = What is the acceleration a of block 1?a =

A warehouse worker applies a force F to accelerate two crates, mã and mp, to the right along a rough floor. Crate mд has a mass of 4m, crate mp has a mass of m. Choose 1 answer: A F Which is the correct relationship between the applied force F acting on mд and the force mд exerts on mB? B D MA mB The force Facting on my is smaller than the force that mA exerts on MB. The force Facting on my is the same as the force that mA exerts on MB. The force Facting on my is larger than the force that mд exerts on MB. The answer depends on the relative size of the friction force on MA and MB.

A 32.7-kg crate rests on a horizontal floor, and a 62.0-kg person is standing on the crate. Determine the magnitude of the normal force that (a) the floor exerts on the crate and (b) the crate exerts on the person.
