STEM Lessons for College Students

10.78 .. The solid wood door of a gymnasium is 1.00 m wide and 2.00 m high has total mass 35.0 kg and is hinged along one side. The door is open and at rest when a stray basketball hits the center of the door head-on applying an average force of 1500 N to the door for 8.00 ms. Find the angular speed of the door after the impact. [Hint: Integrating Eq. (10.29) yields _Lz = 1 t2 t1 1gtz2dt = 1gtz2av _t. The quantity 1 t2 t1 1gtz2 dt is called the angular impulse.]

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
