Question

A particle starts from rest at x = 0 with acceleration of -2
ms-2. The time interval after which it reaches at x = -10m is
3.16 second
5 second
2 second
It will never reach at x = -10 m​

Answer 1

Answer:

A particle is thrown towards the x-axis with a velocity of v0. The acceleration of the particle is inversely proportional to the square of the distance from the origin, so a = -2 x2 then at what distance will the particle be fixed? = -10m
