2. Relevant equations

x=x_{o}+v_{o}t+1/2at^{2}

v=v_{o}+at

3. The attempt at a solution

I first found my component velocities and then the time by using the x=.... equation above. I broke it up into 2 parts: the time it took to leave the bridge to the time it was level with the bridge on its downfall and i got 2.94s. Then i found the time it took to go from the point level with the bridge to the water and got .8s. I then added 2.94+.8=3.74s*.

To find the velocity i plugged my numbers in to v=... equation above and got 22.69m/s*.

Someone please check and see if I did this correctly! I'm not sure if I was supposed to break it into 2 parts to find the time!
