V_1_x = -26.8\cos{22^0} I tried to do this equation in my calculator -26.8 divided by cos(22^0). Is this what you ment? I am sorry for all the questions I am tring to really understand physic.

Where did you get -28.6? I tried -28.6cos(22)/26.8= x This is what you ment right?

I just tried to input zero with any equation. The reason i did this was because i don't know what to do. So i was just tring to see if any of the answers would be zero. I don't know which equation to use to start these problems

My home work is aon a site called smart physics. I can in put an answer and it will tell me if I am right or wrong. I put in zero and it didn't work. I don't know which equation to use or how to find which equation to use.

I already tried zero and it didnt work. I don't know what else to try.

So m1v1+m2v2+m3v3/m1+m2+m3

Im not sure where to start this problem. Which equation to use.

An object with total mass mtotal = 14.4 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.9 kg moves up and to the left at an angle of θ1 = 22° above the –x axis with a speed of v1 = 26.8 m/s. A second piece with mass m2 = 5.1 kg moves down and to the right an...
