(b) Draw a free- body diagram for the 4.00-kg crate. Use that diagram and Newton's second law to find the tension T in the rope that connects the two crates. (c) Draw a free-body diagram for the 6.00- kg crate. What is the direction of the net force on the 6.00-kg crate? Which is larger in magnitude, Tor F? (d) Use part (c) and Newton's second law to calculate the magnitude of F. 6.00 kg 4.00 kg T F

Consider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.27 m/s2 and the person has a mass of 79.2 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.
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.

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?
