F=ma
The Attempt at a Solution
According to Newton's 3rd law, the box pushes back on the person 36N. But I don't know how you find how much force the smaller crate exerts on the larger one.
okgo said:I'm not sure I totally understand how they got 30N as an answer. Our test is coming up soon and I was worried if the multiple choice might be closer to the real answer like C. 25 D.33
Weight is a measurement of force so I used w=mg. 20kg*9.8=196N ??
The formula for calculating net force is F=ma, where F is the net force, m is the mass of the object, and a is the acceleration.
To solve for net force using the F=ma formula, you will need to know the mass of the object and its acceleration. Simply plug in these values into the formula and solve for F.
Yes, net force can be negative. A negative net force indicates that there is a force acting in the opposite direction of motion, causing a decrease in speed or a change in direction.
The unit of measurement for net force is Newtons (N). This is derived from the formula F=ma, where force is measured in Newtons, mass in kilograms, and acceleration in meters per second squared.
Net force is the overall force acting on an object, resulting from the combination of all individual forces acting on that object. It takes into account both the magnitude and direction of each individual force, resulting in a single net force value.
