1.0\,\text{kg}

cart moving with

5.0\,\text{m\,s}^{-1}

on a smooth horizontal track collides head-on with a stationary

2.0\,\text{kg}

cart. The coefficient of restitution between the carts is

e

. If

40\%

of the initial kinetic energy of the system is lost in the collision, determine the value of

e

(correct to two significant figures).
