## How much kinetic energy is lost - friction, Physics

Assignment Help:

A dartboard with a mass of 2.20 kg is suspended from the ceiling such that it is initially at rest.

A 0.030-kg dart is thrown at the dartboard with a velocity of 1.3 m/s.

After the dart hits the dartboard, the dart and the board initially move with a velocity of 0.025 m/s.

How much kinetic energy is lost in the system?
