calculus statics

A ball is projected vertically upwards with an initial speed of 10 m s−1 at a height of 2.5m above the ground. In part (a) ignore all frictional forces.(a) (i) Draw a force diagram for the ball while it is in motion. [1](ii) Define appropriate coordinate axes and an origin, and state theinitial velocity and initial displacement in terms of the unitvectors and origin that you have chosen. [2](iii) Determine, in terms of the magnitude of the acceleration due togravity, g, the maximum height that the ball reaches above thepoint of projection, and the time taken to reach this position. [3](iv) Determine the speed at which the ball hits the ground, correct to two decimal places, taking the value of g to be 9.81m s−2. [2]In the remainder of the question revise this model by taking air resistanceinto account.Model the ball as a sphere of diameter D and mass m, andassume that the quadratic model of air resistance applies.
