1.      A motorcycle starting from rest, speeds up with a constant acceleration of  2.6 m/s2. After it has traveled 12o m, it slows down with a constant acceleration of -1.5 m/s until it attains a velocity of 12 m/s. What is the distance traveled by the motorcycle at that point?

Hint. Do not use decimals, leave square roots indicated.

I need to use definite integrals to answer this question please!
