Asked by Jane
"A moving object has a kinetic energy of 145 J and a momentum with a magnitude of 40.0 kg·m/s. Determine the mass and speed of the object."
I simply cannot figure it out. I know that KE=.5mv^2 and that p=mv but I can't seem to piece it together. Please explain?

40=mv
145=.5mv^2
divide the second equation by the first.
145/40=.5v
v=290/40 m/s
then figure m.
