You need to find an expression for so that you can compute the expressions in the other thread on which you commented. How can you do that, do you think?
Ok, this one has got me stumped. I have no idea what to do really.
Given
where x and y are in meters and y is positive,
what is the normal component of the acceleration when
I found when x = 3, y = 14.491 which i can find the magnitude and angle to plot on the x-axis. And i know i need velocity to define n-t direction, but thats all I got. I guess im confused from how its set out.
How do i approach this question?
