A 120-kg roller coaster cart is being tested on a new track, and a crash test dummy is loaded into it. The roller coaster starts from rest at point A which is 35m above the ground. The cart observed is to roll down the track to point B, which is 10 m above the ground. In your own words, what physics idea would you be able to use to predict how fast the cart is moving at point B?
