Questions
A particle is projected with velocity along x-axis. A damping force is acting on the particle which is proportional to the square of the distance from the i.e. The distance at which the particle stops: [Take m =1kg]
detailed solution
Correct option is D
Given : ma=−αx2⇒mvdvdx=−αx2⇒m∫v00 vdv=−α∫0x x2dx ⇒m0-v022=-αx33-0⇒x=3mv022α13⇒x=3v022α13 [put m =1kg]Similar Questions
