10. Two crates, one with mass 4.0 kg and the other with mass 6.0kg, are on the frictionless surface of a frozen pond, connected by a light rope. A woman wearing golf shoes (so she can get traction on the ice) pulls horizontally on the 6.00kg crate with a force F that gives the crate an acceleration of 2.50 m/s². a. What is the acceleration of the 4.00 kg crate? b. Draw a free-body diagram for the 4.00kg crate. Use that diagram and Newton's second law to find the tension 7 in the rope that connects the two crates. c. Draw the free-body diagram for the 6.00-kg crate. What is the direction of the net force on the 6.00kg crate? Which is larger in magnitude, force 7 or force F? d. Use part (c) and Newton's second law to calculate the magnitude of the force F. 6.00 kg 4.00 kg T Figure 2 F
