How large a force is required to accelerate a 1300-kg car from rest to speed of 20m/s in a distance of 80m ?

Just before striking the ground, a 2.0-kg mass has 400 J of KE. If friction can be ignored, from what height was it dropped ?

1. Using the definition C = Q/V, show that for a SERIES connection of capacitors:

1/C1/C1+1/C2. What does this equation mean? What happens to C as more and more capacitors are connected in series? 2. Using the definition C = QV, show that for a PARALLEL connection of capacitors: C = C1 + C2. What does this equation mean? What happens to C as more and more capacitors are connected in parallel?
