Kinematics problem - changing coordinates

[StillAnotherDave]

Homework Statement

Is it possible to solve this problem by changing the coordinate axes?

Relevant Equations

Kinematic equations

Hi folks,

See below for a solved question finding the down slope distance of an arrow. How easy would it be to solve this question by making the x-axis the slope direction?

One way to find out is to do it ! You'll have acceleration on two axes.

Aha, yes horizontal acceleration is what I didn't consider.

It's interesting to see something as advanced as this done with specific numbers, rather than with general variables. It can't be any harder to do it generally.

But, I guess "plug-n-chug" is what's taught these days.

Or is the exercise from an old book ?
