2. The object shown in the strobe-motion t, s v, m/s y, m diagram (Figure 1.9) has been dropped from 0 0 0 rest at time t = 0 s and falls freely with an acceleration of 10 m/s2. Let the downward direction be the +y direction and assume that the strobe light flashes once every second. a. Complete the column with the heading "t, s". b. Write the instantaneous speeds of the object in the column with the heading "v, m/s". c. Use Equation 7 to complete the column whose heading is "y, m". Figure 1.9 Lab 1 Linear Motion
