+4 A 1210 kg rollercoaster car is moving 8.31 m/s. Before entering the station, it first rolls up a 2.26 m hill. How fast is it moving then?
(Unit = m/s)
I'm trying to help my stepdaughter solve this and I am completey dumbfounded when it comes it Physics. If someone could work this out for me, I would be extremely appreciative.
