Question: The figure below (not to scale) shows an acceleration-time graph of a body. a (m/s^2), 30 7 t(s) If the initial velocity was zero,

The figure below (not to scale) shows an acceleration-time graph of a body. a (m/s^2), 30 7 t(s) If the initial velocity was zero, a(0) = a0 = 8.3 m/s^2, a(7) = a7 = -2.2 m/s^2 and the particle's acceleration returns to zero at t = 10s, what will the body's velocity be at t=10 s? Express your answer to three significant figures in units of m/s (but do not write the units with your answer).
