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]

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]
