AIIMS2016PhysicsMotion in One Dimension
A body moves from rest with a constant acceleration. Which one of the following graphs represents the variation of its kinetic energy K with the distance travelled (x) ?
Correct answer
2
Step-by-step solution
aligned & K= 1 2 m v^2, where v=0+a t & K= 1 2 m(a t)^2= 1 2 m a^2 t^2 & As a= [L T⁻² ]= constant & L T^2 & K= 1 2 m a^2 . L or K L or x . aligned
