Homework Statement
This isn't really coursework or homework, but something I really want to confirm.
There is a ramp of height h on an angle θ that a car is placed on that leads to a wall perpendicular to the ground (looks like this: |∠). When calculating velocity of the car when it hits the wall using E = E', do I need to account for θ?
Every instinct I have says yes, but I want confirmation.
Homework Equations
E = E'
The Attempt at a Solution
E = E'
mgh = 1/2 mv^2
Solve for v .. doesn't really matter what it is.
Is the velocity of the car in a momentum equation (p = mv) equal to v or is it equal to v*cosθ?
