Question

a paricle is moving along path y =x square in x -y plane with constant speed of 10 m/s. what will be its magnitude of acceleration when it is at x =0.(assume that all units are in SI)​

Answer 1

... SOLUTION:- ....

Given, y=9x2

Also, x-component of velocity  vx=dtdx=0.333 m/s

Differentiating with respect to time t, we get  dtdy=18xdtdx

⟹  vy=18xvx=18x(0.333)=5.994x

As x component velocity is constant, so acceleration has only y-component. 

So, a=ay=dtdvy=5.994dtdx=5.994vx  

⟹  a=5.994(0.333)=1.996∼2 ms−2
