F=ma, W=mg calculations

Draw

Mr. Welkener has a mass of 65kg. How much net force is needed to accelerate him around the room to 15 m/s^2?

For full credit, you will need to 1) Show your work, and 2) Include the proper units.

(Hint: in Physics, Force is measured in Newtons!)

​Tips for Making Great Videos

1. ​Follow all the instructions given

   1. Check the rubric

   2. Check the guidelines (Google doc on 'Science Byte videos')

2. Include "breathing space" in your video

   1. Your video should feel clean, NOT rushed or cluttered

   2. Make sure there is no 'dead space'

   3. If you have too much 'dead space', add some nice audio, music, or image(s)

3. Ask your teacher for help BEFORE turning in the assignment.

​And don't forget...

​Make sure to include 1 fully worked-out math problem in your video.

This should be a math problem that you created and solved yourself, using one of the formulas we have discussed in class.

F = ma W = mg


a = (v_f - v_i)/t speed = distance/time
