(8%) Problem 6: The velocity of a moving obiect was measured at various times and the results are shown in the table and graphed in the Velocity vs Time gure Time (s 0.00 10.2 19.8 31.5 39.9 49.5 60.1 70.2 250 240 230 220 210 200 190 180 170 160 eloc 165 207 228 239 246 249 250 250 0.00 10.00 20.00 30.00 40.00 50.00 60.00 70.00 Time (s) ©theexpertta.com By taking the slope of the curve, determine the acceleration, in meters per second squared, at time 10.0 s Grade Summary Deductions Potential 0% 100%

Explanation / Answer

Acceleration = slope of v-t graph =207-165/10=4.2 actually there is some problem because acc to data given at 10.2s value of v is 207 but acc to graph its at 10s

x=At+Bt^2...........eq 1

Differentiate eq 1 with respect to time

V=dx/dt=A+2Bt
