Transcript

The problem. Here is the problem: A net force of 2300 N acts on a 1300 kg car. What is its acceleration? Use the Newton prime s second law formula, rearranged for the unknown, in SI units.

Step by step. Formula: Newton prime s second law. Rearrange for acceleration a. Substitute the known values.

The answer. So the answer is acceleration a equals 1.76923 m/s squared. Newton prime s second law links the net force on an object to its acceleration: F equals ma. Force and acceleration point the same way, so a negative force gives a negative acceleration. One newton accelerates one kilogram by 1 m/s squared.

Check. Substituted every value back into the formula: both sides agree, which checks out.

About newton's laws and weight

Use F = ma and W = mg to find force, mass, acceleration and weight.
