A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground, If Upton free falls for 2.60 seconds. The takeoff speed for this plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length for the runway?

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
