[6 pts] An object moves such that its acceleration is given by the function a(r) : 5111(Er] meters per second per second. The objects initial velocity is 0 meters per seoond. The time variable is measured in seconds. a. Use integration to nd the velocity of the object as a function of time. HINT: This is an initial value problem. b. Find the displacement of the object on the interval from 0 to 4 seconds. Round to 2 decimal places. HINT: Displacement is net change in position. c. Find the average velocity of the object on the interval from D to 4 seconds. Round to two decimal places. >> I\" C) <
