The instant take off speed is 2.96 m/s
What is force applied over distance?
- It is intimately correlated with both the amount of force applied to the item and its motion. The equation below may be used to compute work: Work is equal to force times distance. The Newton meter is the SI unit of work (N m). When an item is moved across a distance of 1 m with 1 N of force, one joule is equal to the amount of work that is accomplished.
- The forces and motion in a standing vertical leap are both vertical. F = FGRF - mg, where FGRF is the vertical ground reaction force applied to the jumper and mg is the jumper's body weight, results in a vertical force on the jumper.
Given :
Weight of the Basket ball Player = 950 N.
Force Applied on the Floor = 1800 N
over Vertical distance = .5 m
resultant force f = 1800 N - 950 N = 850 N
work done = 850 * 0.5 m =425 J
kenetic energy = 1/2 mv^2= 425
mass = 950/ g = 96.9
v^2 = 425 * 2/ 96.9
v= [tex]\sqrt{8.78}[/tex] = 2.96 m/s
instant Take off is 2.96 m/s
