Q1. If air drag is negligibly small, how fast is sequoia cone moving while it reaches the ground if it dropped from the top of a 114 tree?

Q2. A positive charge of q = 3.5 µC is pulled on by two negative charges. One, -2.0 µC, is 0.050 m to the north and the other, -4.0 µC, is d = 0.029 m to the south. What total force is exerted on the positive charge?
