Ok the problem is:
Energy is to be stored in a flywheel in the shape of a uniform solid disk with a radius of 1.30 m and a mass of 72.0 kg. To prevent structural failure of the flywheel, the maximum allowed radial acceleration of a point on its rim is 3600 m/s^2.
What I did was solve for...
ya sorry I had it written 9.7kg*2, I did use 19.4.
But for the x_f1 I put it to -470.4m because I put the center of mass that I found as the origin in a new axes for calculating x_f2's position.
so 776.1m became 0, which means that 776.1m-305.72m became x_f1 and since it's to the left of...
Hi, sorry stuck again!
Here is the problem:
A projectile of mass 19.4 kg is fired at an angle of 57.0 degrees above the horizontal and with a speed of 81.0 m/s. At the highest point of its trajectory the projectile explodes into two fragments with equal mass, one of which falls vertically...
awww I see, so if I want the initial position of the canoe to be 0 I would have to set the coordinate in the center of the canoe making the woman's initial position -1.5. Ok, well that makes sense, thanks Radou.
Well I included the mass of the canoe when I divided. I have the initial position of the canoe equal to 0 is there a different number I should use for that?
Hi there,
I have a question about what I'm doing wrong with the following problem:
A 45.0-kg woman stands up in a 60.0-kg canoe of length 5.00 m. She walks from a point 1.00 m from one end to a point 1.00 m from the other end. If you ignore resistance to motion of the canoe in the water...
