1. An electrically charged macroscopic spherical oil drop of mass M=5.449x10^(-14) kg is released from rest between two electrically charged horizontal plates that produce a uniform electric field magnitude of E=1.667x10^6 N/C that is directed vertically upward. If, after release, the oil drop...

Hello, I've been stuck on this problem and would really appreciate if someone could help me: A block of mass MB = 4.75 kg is initially at rest on a level rough surface for which the coefficient of kinetic friction is given by uk = 0.455 . Two bullets of equal mass Mb = 0.023 kg are moving...
