**physics homework help plz projectile motion**

## Homework Statement

a biker is iding on a flat stretch of lan 50 m long, without friction. he then goes up a flat ramp that its surface is 30 degrees from the ground (no friction) the biker then leaves the ramp and goes 37.5 m across to the other side, and lands on a flat surface that is level with the top of the ramp where the biker rode off of. what is the constant acceleration the biker needs to acclerate while riding through the 50 m flat stretch to successfully land on the other flat surface 37.5 away from the end of the ramp? (no acceleration at ramp)

## Homework Equations

v final squared - v initial squared= 2ad (for beginning 50m)

displacement y= vt-4.9t squared

displacement x= vt

## The Attempt at a Solution

v final squared - v initial squared= 2ad (for beginning 50m)

displacement y= vt-4.9t squared

displacement x= vt

i then said v leaving the ramp was v sin 30, so v= v sin 30 for the last two equations

but im not sure when it leaves the ramp, should i call the speed v sin or v cos? or just v??

*this is my 1st time posting so srry if its confusing to read through this. thanks
