Homework Statement
Two particles with masses 2m and 3m are moving toward each other along the x-axis with the same initial speeds v. Particle 2m is traveling to the left, while particle 3m is traveling to the right. They undergo an elastic, glancing collision such that particle 2m is moving...

A sky diver of mass 81.5 kg jumps from a slow-moving aircraft and reaches a terminal speed of 50.0 m/s.
(a) What is the acceleration of the sky diver when her speed is 30.0 m/s? Homework Equations
mg = bv
where b is the friction constant
and v is the terminal velocityThe...
Thanks Tac Tics.
But it seems you are making this more complicated than it should be. This is supposed to be simple 1 dimensional motion problem, no need for Work or even Force.
Is it not true that given 2 velocities, the initial and the final, that if you find the average of those and then...
I cannot figure out what is wrong! (frustrated)
