A 400. kg cart slides along the track shown in the image, beginning at point A. It starts from rest and experiences no friction or air resistance. Once it gets to the point marked B, what is the cart’s speed AND the value of the normal force? Because of HuskyCT's limitations with multiple answer questions, please enter your two answers as numbers only, and with exactly 2 significant figures each. The cart has a speed of ----- ??m/s. The value of the normal force at point B is ------- ?N.
