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.
