8. An object has the acceleration graph shown in Figure P2.23. Its velocity at t=0s is vx = 2.0 m/s. Draw the object's velocity graph. ax (m/s) 2. 1 0 -1 -2 t(s) 8 10 FIGURE P2.23 9. Blood is accelerated from rest to 30.0 cm/s over a distance of 1.80 cm by the left ventricle of the heart. Assuming constant acceleration, how long does this motion take in seconds? 10. A ball is dropped from rest off a cliff. After one second, how fast, in meters per second, is the ball traveling in m/s if we neglect the effect of air resistance?
