A spy in a speed boat is being chased down a river by government officials in a faster craft. Just as the officials' boat pulls up next to the spy's boat, both boats reach the edge of a 4.8 m waterfall. The spy's speed is 16 m/s and the officials; speed is 26 m/s. How far apart will the two vessels be when they land below the waterfall? The acceleration of gravity is 9.81 m/s . Answer in units of m

  • physics -

    how long does it take to fall 4.8m?

    d= 1/2 g t^2
    4.8=4.8t^2 t=1sec

    so now the boats distance apart is relative speed*time= 10m/s*1s=10m
