- The more inertia a body has, the more resistance it will have to displacement mass acceleration O velocityFrancesca dangles her watch from a thin piece of string while the jetliner she is in accelerates for takeoff, which takes about 11 s. Estimate the takeoff speed of the aircraft if the string makes an angle of 25 degrees with respect to the vertical.If the net force is zero, then the speed ○ velocity acceleration All of the above of the object will be zero.
