A basketball player jumps straight up for a ball. To do this, he lowers his body 0.300 m and then accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a vertical velocity sufficient to carry him 0.900 m above the floor. (a) Calculate his velocity when he leaves the floor. (b) Calculate his acceleration while he is straightening his legs. He goes from zero to the velocity found in part (a) in a distance of 0.300 m. (c) Calculate the force he exerts on the floor to do this, given that his mass is 110 kg.

A box has a mass of 67 kg, a force of 91 N is applied to it at an angle of 45º, an object moves on a surface of 29 m with a coefficient of kinetic friction = 0.04 and where its initial velocity is equal to 13 meters/sec. in said path: Determine the magnitude of the normal (n).

Consider an object of mass m = 2kg moving up a ramp with an initial speed (vi) of 10m/s. Suppose that the ramp make an angle θ = 30◦ relative to the ground. Given that the coefficient of static friction and the coefficient of kinetic friction between the surfaces of the ramp and the object are μs = 0.6 and μk = 0.5 respectively. (a) Find the acceleration of the object as it slides up.(b) How far does the object move along the ramp?(c) Does the object move down the ramp after it reaches the maximum height (Justify your answer with calculation)?
