A 4.00 kg cart is pushed against a spring at point A, compressing the spring (with a spring constant of 600 N/m) by 0.816 m. When the cart is released from rest, it moves to the right with a constant speed (assume there is no friction in the wheels). What is the speed of the cart after it is released at point B?
