A 2 kg object is acted upon by a net force of 10 N. What is the magnitude of its acceleration?
Show the answer and explanation
Correct answer
B. 5 m/s^2
Principle or equation
Newton's second law: F_net = m * a, so a = F_net / m.
Why this answer is correct
Given F_net = 10 N and m = 2 kg, a = 10 / 2 = 5 m/s^2.
Example
If a 3 kg object has a net force of 15 N, its acceleration is 15/3 = 5 m/s^2.
