70. Displacement from a velocity graph Consider the velocity function for an object moving along a line (see figure). a. Describe the motion of the object over the interval [0, 6]. b. Use geometry to find the displacement of the object between t = 0 and t = 3. c. Use geometry to find the displacement of the object between t = 3 and t = 5. d. Assuming the velocity remains 30 m/s, for t≥ 4, find the function that gives the displacement between t = 0 and any time t > 4. سارا Velocity (m/s) VA 40+ 30- 20- 10+ 0 2 3 4 5 6 t Time (s)
