Using conservation of energy, determine the velocity of the cart at point B when it reaches the ground? The cart plus occupant has a mass m of 2kg. Just in case you have trouble viewing the picture (Try chrome), at Point A, on the left, the roller coaster cart is on the track headed towards point B on the right at a velocity of 5m/s at a height of 10 meters. At point B to the right, the roller coaster track is on the ground. This should allow you to draw your own picture. It is assumed your answer will be in meters / second. Also, use g=10m/s2.
