Question

A particle moves in a straight line with retardation
proportional to its displacement. Its loss of kinetic
energy for any displacement x is proportional to:​

Answer 1

Answer:

Loss of kinetic energy is directly proportional to x^2*t^2

retardation is directly proportional to displacement(>>this symbol represents direct proptionality)

-v/t>>x

-v>>xt

v^2>>x^2*t^2

and kinetic energy=(1/2)*mv^2
