## Homework Statement

A projectile is shot from the edge of a cliff (h=265m) above ground level with an initail speed of Vi= 115m/s at an angle of 37.0 degrees with the horizontal.

a. Determine the time taken by the projectile to hit point P at ground level?

b. Determine the Range of the projectile as meaured from the base of the cliff

c. At the instant just before the projectile hits point P, find the horizontal and the vertical components of its velocity.

d. What is the magnitude of the velocity?

e. What is the angle made by the velocity vector with the horizontal?

f. Find the maximum height above the cliff top reached by the projectile.

## Homework Equations

a. y=y 0 +v 0 t+(1/2)at 2

b. R=(V o^2 Sin 2∅)/g

c. ?

d. ?

e. ?

f. ?

## The Attempt at a Solution

Sorry if this seems to easy for you, but I'm 48 and my math skills aren't as sharp as they used to be. I am particualary stuck on trying to solve for the time. How do Solve for t? forgot the rules on how to factor out the t, so here is what I had:

y=265m=(69.2087)(t)-(1/2)(9.8)(t)^2
