Check that your answers are sensible, significant figures, units and that you have documented your answer with comments and statements of physical principles. The problem type is free fall uniformly accelerated motion in – the vertical Y direction: = -g = -9.81 m.s-2 and the displacement corresponds to the a s changes in the vertical position of the ball. We can solve the problem using the equations (1) (2) (3) (4) (5) Case (a) Initial state: = 0 = 0 = 0 = -9.81 m.s-2 t s u a = -g Final state when = 1.23 s: = ? m = ? m.s-1 t s v Eq(1) Eq(2) Final state when = -40.0 m (as ball strikes ground): = ? s v = ? s t
