(a) Figure 1 above shows the displacement time graph of the motion of a particle. State the nature of the motion of the particle between: (i) A and B (ii) B and C (iii) C and D (b) A ball is thrown horizontally from the top of a vertical tower and strike the ground at point 50m from the tower. Given that the height of the tower is 45m, determine the: (i) Time taken by the ball to hit the ground. (ii) The initial horizontal velocity of the ball. (iii) Vertical velocity of the ball just before striking the ground. (Take acceleration due to gravity, g, as #10ms^-2#).
