How much kinetic energy is lost in the system

Reference no: EM13659417

A dartboard with a mass of 2.2kg is suspended from the ceiling such that it is originally at rest. A 0.030kg dart is thrown at the dartboard with a velocity of 1.2m\s. After the dart hits the dartboard, the dart and the board initially move by a velocity of0.025m\s. How much kinetic energy is lost in the system?
