Question

The figure shows the velocity as a function of tine for an object. What is the average acceleration during the interval from t = 0 s to t = 20 s? m/s2 Estimate the velocity at t = 4 s. m/s Estimate the velocity at t = 6 s. m/s Calculate the instantaneous acceleration at t = 5 s. (Use your estimates.) m/s2 Estimate the velocity at f = 8 s. m/s Estimate the velocity at t = 12 s. m/s Calculate the instantaneous acceleration at t = 10 s. (Use your estimates.) m/s2 Estimate the velocity at t = 21 s. m/s Estimate the velocity at f = 23 s. m/s Calculate the instantaneous acceleration at t = 22 s. (Use your estimates.) m/s2
