Question

the relation between velocity and displacement of a body is equal to 4 x cube, find its acceleration

Answer 1

I think this answer is right ❤️❤️
Displacement d=kt^3. is given . Here k is proportionality constant. Differentiating w.r.t. t we get velocity v=3kt^2. Now differentiation of velocity w.r.t. time t will give acceleration a=6kt. So, acceleration will be directly proportional to time t elapsed.
