QUESTION 1 Figure Q1 shows the motion of a cannonball is fired from the top of a building's roof with an initial velocity of VA= 120 m/s. i) Compute the horizontal distance, R of the canhonball from A to B, and the vertical and horizontal components of vg before the cannorìball strikes the ground at point B. (C01- PO1)(C3) (12 marks) ii) The cannonball weight is 4 kg and slides from poiht B to C on a 15° inclined surface and stops when it reaches point C. The coefficient of kinetic friction of the cannonball and the plane is Hk 0.3. Using impulse-momentum method, determine the time taken for the cannonball to travel from point B to point C.
