Homework Statement
A boat starts a race at 3 m/s, accelerates uniformly for 10 seconds, then travels with constant velocity for 6 seconds. It then slows uniformly to rest in another 6 seconds. If the boat has traveled a total distance of 225m, find the maximum velocity.
Homework Equations
a(t) = v`(t) = s``(t)
The Attempt at a Solution
Obviously the boat has three phases of motion:
- the initial acceleration
- the constant velocity
- and the negative acceleration until it comes to rest
And I need to find the constant velocity. However I am honestly stuck I do not even know how to approach this question! Please help!
