If a 40 kg person is accelerating at 10m/s^2, then the magnitude of the force acting on him or her is 400 N.

•True?
•False?

True.

To understand why the magnitude of the force acting on the person is 400 N, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a), or F = m * a.

Given that the person's mass (m) is 40 kg and the acceleration (a) is 10 m/s^2, we can calculate the force (F) by substituting these values into the formula:

F = 40 kg * 10 m/s^2
F = 400 N

Therefore, the magnitude of the force acting on a 40 kg person who is accelerating at 10 m/s^2 is indeed 400 N.

force=mass*acceleration

=10kg*10m/s^2=400 N
