    An archer fish launches a droplet of water from the surface of a small lake at an angle of 62° above the horizontal. He is aiming at a juicy spider sitting on a leaf 43 cm to the east and on a branch 30 cm above the water surface. The fish is trying to knock the spider into the water so that the fish can eat the spider.
    (a) What must the speed of the water droplet be for the the fish to be successful?

    Split the motion into constant velocity motion in x and uniformly accelerated motion in y. If you really need more help you'll have to help us by attempting to do the problem and posting the attempt.
