A particle moves along the curve $y=mx^a + c$ with a constant speed $v$. Find the velocity at x=n (in $i cap, j cap$) and acceleration at x=n.
I tried this question as: I found out the slope of curve by differentiating which gives tanθ and we know the resultant is $v$ of both $ vectors(components of velocity)$ so by trigonometry i can find values of i cap, j cap. Is it the correct way to proceed this the of problem? Also i am having problems with acceleration and can you guide me through it?
