18. Refer to Figure 29 to find the magnitude of the displacement during the following time intervals. Round answers to the nearest meter. a. \( t=5.0 \mathrm{~min} \) and \( t=10.0 \mathrm{~min} \) b. \( t=10.0 \mathrm{~min} \) and \( t=15.0 \mathrm{~min} \) c. \( t=25.0 \mathrm{~min} \) and \( t=30.0 \mathrm{~min} \) d. \( t=0.0 \mathrm{~min} \) and \( t=25.0 \mathrm{~min} \) Velocity v. Time Figure 29 72. A stone that starts at rest is in free fall for \( 8.0 \mathrm{~s} \). a. Calculate the stone's velocity after \( 8.0 \mathrm{~s} \). b. What is the stone's displacement during this time?
