Projectile Motion! Please Help!
The acceleration due to gravity can be measured by firing a projectile upward and
measuring the time it takes to pass two given points in both directions. The figure below
is a plot of height versus time and shows that the time the projectile takes to pass a
horizontal line A in both directions is TA, and the time it takes to pass a horizontal line B
in both directions is TB. Derive an expression for g, the acceleration due to gravity. Your
expression should involve only h, TA, and TB. State any assumptions you make.
Dont even know where or how to start! Please Help! thanks
