A basketball player can jump vertically 0.9 m. Assume that the jump interval (from lowering the body to his feet taking off) lasts for 0.3 s and the mass of the player is 90 kg. Ignore air resistance.
Determine the force that the the player exerts on the surface when he jumps.
Determine the force that the surface exerts on the player when he jumps.
Determine the force that the surface exerts on the player when he is landing back on the floor.
How would the answers change if air resistance is considered?
