In order for the man to move at constant velocity the net force on him must be zero. He can't move at a constant velocity if there is an unbalanced force on the right (think about it: the right side of the rope would accelerate but the left side wouldn't? would the rope not rip in this case?)...
1. Homework Statement
I don't understand why when we derive the velocity equation of motion in polar coordinates we start with position equal to R times R hat and not (theta times theta hat + R times R hat).
2. Homework Equations
3. The Attempt at a Solution
Is there an...
I'm currently finishing up my B.S in Physics (going into the last semester of Junior year) and plan on getting a Masters in Computer Science concentrating on software engineering. I'm curious if anyone else has made a similar career choice and how it worked out. Also, which...
You're not "adding vectors." You need to apply conservation of momentum. Momentum is a vector quantity. Thus if you know the momentum vector before the collision, the sum of the individual momenta afterwards must equal what?
