Answer 1

Answer:

follow me on insta I'll say answer .....

Answer 2

Answer:1/x³

Explanation:

x²=t²+1

Taking its differentiation

2x*(dx/dt)=2t

x*(dx/dt)=t

Again, taking differentiation for acceleration

x*(d²x/dt²)+(dx/dt)²=1

x*(d²x/dt²)=1-(t/x)² [since x*(dt/dx)=t]

(d²x/dt²)={1-(t/x)²}/x

(d²x/dt²)=1/x-t²/x³

Putting t²=x²-1

(d²x/dt²)=1/x³

.... Hope this will help you
