Question

A heavy ball with a mass of 6.0 kg is observed to accelerate at a rate of 4.0 m/s2. What is the size of the net force acting on this ball?

Answer 1

Question 32089

According to 2nd Newtons Law, $\vec{F} = m\vec{a}$ , where $\vec{F}$ is the net force, exerted on the object, $m$ is the mass of the object, $\vec{a}$ is the acceleration of the object. Thus, $|\vec{F}| = m|\vec{a}| = 6kg\cdot 4\frac{m}{s^2} = 24N$ - This is the net force acting on ball.
