A 67.0 kg crate is being raised by means of a rope. Its upward acceleration is 3.50 m/s2. What is the force exerted by the rope on the crate? 

Newton's Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” We calculate as follows:

F = ma = 67.0 kg (3.50 m/s^2) = 234.5 J

The answer should be a.
