#$&* course Phy 201 9/23 441 An airplane on a runway has velocity 10 m/s at clock time t = 8 sec and velocity 20.5 m/s at clock time t = 15 s. Find its average velocity and its average acceleration during this time interval, and determine whether the acceleration might be uniform, if the distances from a certain roadkill on the runway are 93 meters and 132 meters at the respective clock times.Vave = ds/dt
