A 40.0-kg crate is being raised by means of a rope. Its upward acceleration is 2.00 m/s². What is the force exerted by the rope on the crate? A) 80.0 N B) 312 N C) 392 N D) 472 N E) 552 N

Question

Quizplus · Accepted Answer

The force exerted by the rope can be calculated using F = ma + mg, where m is the mass (40.0 kg), a is the acceleration (2.00 m/s²), and g is the acceleration due to gravity (9.8 m/s²). Thus, F = 40.0 kg * (2.00 m/s² + 9.8 m/s²) = 472 N.
