A ball is projected vertically upwards with an initial speed of 10 m s1 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. (ii) Dene appropriate coordinate axes and an origin and state theinitial velocity and initial displacement in terms of the unitvectors and origin that you have chosen. (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. (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 s2. 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.
