## Homework Statement

Find the arc length of the projectile from launch until the time it hits the ground, given that

0 V is 100 feet/sec and is 45 degrees.

## Homework Equations

Arc Length= ∫_a^b▒√(█(1+(f^' (x) )^2@)) dx

Arc Length of Curve= ∫_a^b▒〖v(t)dt=∫_a^b▒√((dx/dt)^2+(dy/dt) )〗^2 dt

i know these aren't pretty versions of the arc length equations, sorry about that.

## The Attempt at a Solution

i'm not really sure how to go about plugging in what i was given into the equation. need help ASAP. thank you
