Question

A particle moves in a straight line so thatits displacement x metre at timr t second is given by t=(x^2 - 1)^1/2. Its acceleration in ms^-2 at time t second is

Answer 1

Explanation:

first of all you need to convert displacement in terms of time which you can see I have done in the step 4 and then you need to differentiate this expression to get velocity in terms of time and differentiate the resulting in expression one more time to get acceleration in terms of time
