What will be the acceleration of a skydiver when air resistance builds up to 86% of her weight? assume the acceleration due to gravity is 10 m/s 2 . answer in units of m/s 2 ?

Force equals mass times acceleration, F=ma. Rearranging the equation, acceleration = force divided by mass, a=F/m. The skydiver's mass remains constant; therefore, her acceleration is proportional to the total force acting on her body. The total force acting on the skydiver is equal to the force of gravity, which is the same as the skydiver's weight, minus the force of air resistance. When the air resistance builds up to 86% of her weight, the total force equals 14% of her weight (100% - 86%). Her acceleration is 14% of the acceleration due to gravity. a = 0.14 * 10m/s^2 = 1.4 m/s^2.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
