I currently have a B+ average. Is this good for an engineering student. Will I be able to get a good job with these kinds of grades?

Yes, but rounded up it is 1.7 m/s so b is the answer. Good luck!

Momentum must be conserved. For part a pi=pf, where pi=m1v1+m2v2. You know the collision is ineslatic so the 2 gals move off together so pf=vf(m1+m2) where vf is your unknown. Solve for vf. I get 1.66 m/s

Homework Statement If the axis of rotation of a physical pendulum is placed closer to the COM, is the period of rotation longer? If it originally starts .5m from the COM the moves .3M from the COM the peroid shoud be longer right? I keep getting a longer period when the axis of roatation is...

Thank you it finally clicked, your help is much appreciated!

I think i should find the max pe. I am just confused on what numbers to use

I know that the kinetic energy plus the potential energy is equal to the totalt energy. I know the easiest way to solve the problem would just be to find one of them at the max. I am just confused on which one to solve for and how. My teacher did a really bad job on explaning this chapter and I...
