- Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.A basketball player of mass m=88.4 kg jumps straight up for a ball. To do this, he lowers his body d1=0.44 m, then he accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a speed sufficient to carry him d2=0.56 m above the floor. Write an expression for the speed v with which the basketball player leaves the floor. Write an expression for the speed v with wiich the basketball player leaves the floor. Write an expression for the acceleration, a, of the basketball player during the leg-straightening. Write an expression for the force upward force, FN, exerted on the basketball player by the floor during the leg straightening. What is the magnitude, in newtons, of the force FN while the player is straightening his legs?A 0.697 kg football is thrown upward with an initial speed of 49.7 m/s.
