Скачать или смотреть Physics Problem Walk-Through - Work Energy Power - Work Done on a Computer Dragged by a Conveyor

A boxed 10.0 kg computer monitor is dragged by friction 5.50 m upward along a conveyor belt inclined at an angle of 36.9° above the horizontal. If the monitor’s speed is a constant 2.10 cm/s, how much work is done on the monitor by
(a) friction
(b) gravity
(c) the normal force of the conveyor belt?

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.
