Physics momentum/ speed question. Need help!
A woman with a mass of 40 kg runs at a speed of 9 m/s and jumps onto a giant 30 kg skateboard initially at rest. What is the combined speed of the woman and the skateboard?
Momentum= mass x velocity. I can use this to find the momentum of the woman before she jumps onto the skateboard. But what do I do after this??
Momentum of woman= 40 kg x 9m/s. 360 kg * m/s. what I do from here?! Any help would be nice :)
