I have to admit, I am currently in Honors Physics 2, And on my first test on momentum and impulse I got a D+, yes my first ever, its rough, but I wll try my hardest from now on and I will always ask questions here first! The amount of people willing to help on this site is awesome, I for each...

Explain why a point on the rim of a tire has an acceleration when the tire is on a car that is moving at a constant linear velocity :cry: :smile: :mad: :rolleyes: :approve:

A thin rod rotates at a constant angular spped. COnsider the tangential spped of each point on the rod for the case when the axis of rotation is perpendicular to the rod (a) at its center and (b) at one end. Explain for each case whether there are any points on the rod that have the same...

is the answer to the first [roblem 4 m/s backwards

WHAT Formula should I use

i am having trouble finding the final velocity of the astronaut though

Please help An astronaut , 80 KG, is carrying a bag which is 20 KG, walking at a speed of 2 M/S toward a station, He throw the 20 KG bag forward at 6 M/s, what is his final velocity and direction(away from station, toward station) heres another one an astronaut is walking at .15 M/S...

1. ON a distant asteroid, a large catapult is used to "throw" chunks of stone into space. COuld such a device be used as a propulsion system to move the asteroid closer to earth? (need help in terms of momentum,impulse, and all that)

In the equation y=c^nat^2, in other words... Y equals C to the N power times A times T to the second power, you wish to determine the integer value (1,2,etc.) of the exponent N. The dimensions of Y,A,and T are known. It is also known that C has no dimensions. Can dimensional analysis be used to...
