Should you consider anything before you answer a question. moving than to keep it moving at a constant velocity? After. Assume the positive direction is downward. Which kinematic equation would you use to find the velocity of a skydiver 2.0s after she jumps from a plane and before she opens her parachute? Describe what happens to her velocity as she opens the parachute. This is because, when the parachute opens, it covers a large surface area which leads to increase in air resistance acting on the total mass (skydiver + parachute).
