Thanks for your input man, much appreciated. I'll bring my attempt at the solution to a TA and see what they have to say about it.

I assumed that when both players collided and the helmet went flying off, the total mass would be 80kg + 90kg - 2kg as they were sliding on the ground. I also assumed that both 80kg and 90kg are the masses of each player fully equipped. You're right. I forgot to take into consideration the...

Given (V0) from the equation above, I would then use: Σp = m1v1 + m2v2= (m1 + m2) v0 Σpx = m1v1 + 0 = (m1 + m2) v0 cos 45° (Velocity of player 1) Σpy = 0 + m2v2 = (m1 + m2) v0 sin 45° (Velocity of player 2)

Not at this point. But it wouldn't surprise me if I needed to use concepts that I haven't specifically learned yet because it is a bonus question. So just to make things clear, I should not be using the equation below in order to determine the velocity of the collision: Wf = 0 - Ki Uc...

Hi. Thanks for answering. Not that I can think of. The only formula in the collision section of my book that contains the coefficient of friction (Uc) is that one. : -Uc (m1 + m2) (g) (d) = - [(m1 + m2)(vo2)/2] (d is the sliding displacement)

Homework Statement A football player (90 kg) moving east collides with another football player (80 kg) moving north. When both players collide, a helmet (2 kg) is ejected south at a velocity of 5 m/s. If both players fall to the ground and slide a distance of 2 m North-East with a friction...

Thanks for your answer. I calculated the uncertainty in the volume by using partial derivatives as it is shown in my lab tutorial, see the uploaded pdf for the exact formula. I've also checked my answer with the Excel error analysis calculator and the Python Error Propagator Calculator and they...

Hi, I've just had my first lab in physics and I'm having a bit of trouble understanding how to determine the significant figures of my final answers and transforming them in scientific notation. For example: Homework Statement [/B] I had to measure three sides of a parallelepiped with a...

Hi, I'm having quite a bit of trouble finding the propagation of uncertainty (using partial derivatives) of the volume of a hollow cylinder. The examples in my tutorial only demonstrates how to find the propagation of uncertainty on simple operations such as x + y, x/y, etc... 1. Homework...

If I were to throw an object in the air from the ground and it would reach 50% of its maximum height in 2 seconds, how does one find the object's total maximum height and total travel time? This is the last question in my 1D kinematics chapter. I've been successful in resolving my other...
