Astudent throws a 0.2 kg dart at a 1.2 kg dartboard suspended by a pair of chains from the ceiling. (a) if the dart was travelling horizontally at 9 m/s just before it hit the dartboard, how fast is the dartboard moving after the dart hits and sticks? (b) how high will the dartboard and dart now rise? (c) by calculations using your answer to part (a) and (b), is this collision elastic or inelastic?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
