Homework Statement
I just took the test, but I can't remember the question word for word, it was along these lines though: You are standing on bus. It suddenly brakes what is the force that makes you lean forward?
A: Kinetic friction of your shoes on the bus floor
B: Static friction of your...
I got it, thanks so much for the pointers. I actually didn't like the equations I had, so I googled some transformed equations and this one was really easy:
d=vi+vf/2 *t
I know my initial velocity is 4.7m/s and the final velocity must be 0 to be stopped. Then I have the distance of 0.12m...
Thank you gneill, I will take a closer look. I guess my mistake was that I used an equation with 2 unknowns, I think I should be able to figure this out. This forum is awesome and I hope to be able to return some favors once I learn Physics in the next 3 quarters :D
Thank you gneill for your quick reply. So you are saying a≠g so then I would have two unknowns, the time and the acceleration?
Part C is asking for the acceleration, but I need to get the time first, correct?
I have 4 constant acceleration equations from class, none of which have an...
Homework Statement
A cat drops from a shelf 3.7ft above the floor and lands on all four feet. His legs bring him to a stop in a distance of 12cm.
Part A: Calculate his speed when he first touches the floor (ignore air resistance).
Part B: Calculate how long it takes him to stop.
Part C...
