a girl on a bridge 51 m above the water drops a small bag of diamonds off the bridge. At that instant, a boat whose deck is 1.0m above the water, is located 15 m from directly under the bridge. At what constant speed must the boat move toward the bridge if it is to catch the diamonds? Thanks so much for the help... I think the girl dropping the diamonds is a free fall problem so I would use a=-9.8 m/s^2 I think the boat is a constant velocity problem and I would use... well I don't know what to do really :o( The equations I'm allowed to use are Vav=delta X/delta t Speedav=dist/time Vf=Vo+a*t X=Vo*t+.5*a*t^2 Vf^2+ Vo^2+2*a*X Thanks again!!!...
