That makes sense. However, when I solve for m1/m2 I get (.5vf^2 + v^20/(v^2-.5vf^2) when I need an actual ratio.

Homework Statement Two objects moving in opposite directions with the same speed undergo a totally inelastic collision, and half the initial kinetic energy is lost. Find the ratio of their masses, m1/m2. Homework Equations m1v1+m2v2=(m1+m2)vf The objects are moving in opposite directions...

Yup. I think the professor may have made a mistake. I'll take it to him. Thanks!

Homework Statement What is the acceleration (in m/s^2) of a 10 kg mass moving with speed 2 m/s in uniform circular motion about a circle of radius 2m? Homework Equations F=ma a=v^2/r in uniform circular motion The Attempt at a Solution Seems simple enough. To find the...
