Question

heya...gud mrng ... the question is- in case of a motion, displacement is directly proportional to the square of time elapsed .what do you think about its acceleration (constant or variable) . explain why ...​

Answer 1

acceleration is constant

• S=Kt^2, where K is a constant
• v=2Kt,v is velocity
• a=2K, a is acceleration

Answer 2

acceleration is constant as per given displacement is directly proportional to time square so these is case of free fall where acceleration is constant i.e. 9.8 m/s2
