nvm I got it!
Yes, got it! Thank you!
Found the final velocity and angle.. just don't understand the initial KE part now
nvm, got it!
P= mv1i + mv2i = (m1 + m2)vf = 121kg(15m/s) +m2(-16) = (121+m2)(-3.8) and I keep going wrong from here..
nevermind, I got it! Thanks
what would the mass be for ice from water and the specific heat water? That is what I cant seem to figure out. Thank you
