brother i am doing it,...the answer i am getting is 35...teacher says it is 25...what am i doing wrong inthe calculations?

i mean the answer is supposed to be 2.8 m/s...so I am confused to what I am doingwrong...why does the deflection even matter? i mean isn't it just initial and final speeds? and any idea on the first one...

thanks for responding...what do u mean mind the direction?? meaning the 90 degrees? but how? and for the second one i think u mean i did split it into the x,y and it worked... now the third one, is thatright?

is this one like this? .2(8) + .2(6)= 2.8 m/s?

solved thsi one, thanks

ok i solved this one, so don't need it thanks...

A projectile of mass 2.0 Kg approaches a stationary target body at 8.0 m/s. The projectile is deflected through an angle of 90.0 degrees and its speed after the collision is 6.0 m/s. WHat is the speed of the target body after the collision is perfectly elastic? any help on how to do this...

The position of three particles written as (x,y) coordinates are, particle 1 (mass 4.0 kg) at (4.0m, 0m); particle 2 (mass 6.0kg) at (2.0m, 4.0m); particle 3 (mass 3.0 kg) at (-1.0m, -2.0) what is the location of the center of mass? this one too pleasE?? how do you do it...i have answers...

hi guys I am a college junior...taking physics for the first time in my life...its fun...but still tuff...just can i get help with these couple questions..i mean it would be very gracious of any of u to help me out...i know I am new and all, but this place...i was just browsing around and it...
