A force produces an acceleration of 5 ms when applied on a body of mass 4 kg. The
magnitude of the force applied is

F = m • a (I. Newton)

F = (4 kg) x (5 m/s^2)

F = 20 Newtons

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

terd muffin is the correct answer
