Question

A 250 kg engine block is being dragged across the pavement by a sturdy chain with a tension force of 10,000 N, as seen in the free body diagram. Four students make claims about what the motion of the engine block will be based on the information in the diagram. Which student has the correct claim and reasoning? (3c4)
Question 10 options:

Deshaun says, “Since the friction force is greater than the tension force, the object will accelerate to the left.”


Jane says, “Since the tension force is greater than the friction force, the block will move to the right at a constant velocity.”


Kora says, "Since the tension force is greater than the friction force, the block will accelerate to the right.”


Jorge says, “Since the tension force is equal to the friction force, the object will remain at rest.”

Answer 1

Answer:   B

Explanation:

The friction force is less than the tension force
