One way that mathematical models are used by scientists and engineers is to make predictions about how a system will behave. in the video, the engineers use a simple kinematics model to predict how much the glider would need to accelerate as it is pulled along the runway in order to launch. based on the aerodynamics of the glider, the engineers calculated it would need to reach a speed of 40 mph to successfully launch into the air. the roof is 160 feet above the ground, and the runway (built from tables on top of the peak of the roof) was about 60 feet long. the first question the engineers need to figure out is if it is theoretically possible to reach the desired launch speed given the length of the runway and the height of the tower questions 1. given this information, what must the acceleration of the glider be to reach the launch velocity by the end of the runway? (convert all values to si units.) 2. the engineer wants the glider to accelerate at a rate of 1.2g (11.6 m/s"). how does this compare to your result? why would the engineer over-estimate the acceleration?
