Question

The distance covered by a body in time is proportional to the square of the acceleration of the body is what

Answer 1

according to question, distance covered by body is directly proportional to square of the time. e.g.,

, k is proportionality constant.

differentiate with respect to t,

again differentiate with respect to time,

here d²x/dt² is what ? of course acceleration

hence, it is clear that acceleration = 2k = constant

therefore option (c)is correct .
