                     An arrow which is 2.0 m above the floor is released with initial velocity of 30.0 m s  at
                     an  angle  of  37  to  the  horizontal,  towards  a  wall  15.0  m  away  as  shown  in
                     FIGURE 2.17.

                     (a)  At what height will it hit the wall from the surface of the floor?        [5 m]
                     (b)  State whether the direction of the arrow is upward or downward. Explain.   [2 m]
                     (c)  If the mass of the arrow is 100 g, determine the potential energy when it hits the
                          wall.                                                                     [2 m]

               59.  An audience at 15 m away from a singer on stage is not satisfied with the performance
                     of the singer. He threw his packet drink and it hit the singer within 0.80 s after it is
                     thrown. If the angle is 20 from horizontal, calculate

                     (a)  the magnitude of initial velocity of the packet drink.                    [2 m]
                     (b)  the magnitude of final velocity when it hits the singer.                  [3 m]
                     (c)  the height of the stage.                                                  [3 m]

               60.  A bullet is fired from a rifle with muzzle velocity 100 m s  at 15 above the horizontal.
                     Calculate the horizontal range of the bullet.                                  [4 m]

               61.  A long jump athlete take-off at 25 with the horizontal and achieves a jumping distance
                     of 9.12 m.

                     (a)  Calculate the initial take-off speed.                                     [2 m]
                     (b)  Calculate the maximum height of the jump.                                 [2 m]
                     (c)  Suggest TWO ways to increase the jumping distance.                        [2 m]
