A projectile is fired from the top of a 10m high cliff. It has a range of 152m and reaches a maximum height of 8.2m above the cliff top. Determine the time of flight
Is Delta Y =18.2?
Is Uy=10
Homework Equations
Delta Y = Uyt + 0.5 ayt
The Attempt at a Solution
18.2=10t-4.9t2
4.9t2-10t+18.2
Using the quadratic equation
10+-21.37/9.8
t=3.2
Does that seem right
