A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...

In the graph shown below, t0 = 2.1 seconds, the
object stops at 8 seconds, and t' = 22 seconds. First,
find the value of the object's velocity at 2.1 seconds such that
the object's total displacement from 0to 22 seconds is -55.7
meters. Then, using this value find the acceleration
from t = 0 to 2.1 seconds. Answer in
m/s2.
