A horse pulls a cart along a road with a force of 550 lbs. If the horse does 2,674,100 ftlbs of work by the time it stops, how far did the horse pull the cart?
Answer:
When a horse pull a cart the action is on?
A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton's third law the cart must then exert an equal and opposite force on the horse. Newton's second law tells us that acceleration is equal to the net force divided by the mass of the system.

Explanation:
An engine has been diagnosed with blowby.
Technician A says the engine could have a

(D) Neither A nor B
B only, is right technician A says the engine could have a cracked flywheel. Technician B says the compression rings could be worn. Thus, option (b) is correct.
What is technician?A Technician installs, inspects, repairs, or changes complex systems, or performs diagnostic or structural tests. IT Technicians, Lab Technicians, Automotive Engineers, Laboratory Staff, Service Technicians, Clinical Pharmacists, and Dental Engineers are all examples of engineers.
Both technicians agreed that it was because of the differences in the objects. The engine can have a fractured flywheel if the A is being worked on. The compression rings, as the first B, might be worn. The expert was the circles on the pressed.
Therefore, option (b) is correct.
