Physics Problem - Momentum and Impulse - Magnitude of Force - Calculus Based Example

Starting at t = 0 a net external force in the +x-direction is applied to an object that has mass 2.00 kg. A graph of the force as a function of time is a straight line that passes through the origin and has slope 3.00 N/s. If the object is at rest at t = 0, what is the magnitude of the force when the object has reached a speed of 9.00 m/s?

The best way to learn how to solve a Physics problem is to understand examples. NO AUDIO.

All problems are solved following the same basic problem-solving techniques: Break down the problem to identify given and unknown variables. Draw a model if needed. Identify relevant equations and concepts. Solve for the unknown variables. Evaluate equations with given variables.

Follow along as I break down the question and then use standard equations to solve the problem. FF, Pause, or Rewind as needed.

There are often multiple ways to get to the same answer, so don’t be concerned if your path is different, as long as the final answer is the same.
