Unformatted text preview: Lowest Speed: Apex Highest Speed: Initial and End. Q2.) Sometimes two skydivers share one parachute. How much larger is going to be their speed when they touch the ground compared to a single skydiver? Assume that both skydivers have the same weight. Ans2.) The formula to find the final velocity of a body is: = + v2 u2 2gh Here, v=final velocity u=initial velocity g=acceleration due to gravity h=height The speed of a body falling under the influence of gravity is not related to the mass of the body. This can be proved by the above equation too. The final velocity is independent of the mass of the body. Therefore the speed of the person falling alone is going to be the same as the speed of the person falling with two people. Speed of 2 people falling together = speed of 1 person falling alone....
