Hiya! Sam here,...and I'm new. I need help with this online homework problem. To be honeset, I have no idea where to even begin. I've tried the momentum equation where mass times velocity times a proportionality factor gamma, and I think it's the wrong start. Please help?? Question: A skater with a mass of 85kg is moving with a velocity of <3,1,0> m/s at t=3.2 s. If their momentum changes at a rate of <0, 170, 0> kg m/s^2 until t=3.7s, what is their new velocity?
