A force of 350 N causes a body to move with an acceleration of 10 m/s2. What's the mass of the body?

A. 98 kg

B. 3,500 kg

C. 35 kg

D. 3,430 kg

This problem is an application on Newton's second law of motion which states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force.

F = ma

350 = m (10)

m = 35 kg

Therefore, the correct answer is option C.
