Two carts, joined together with a spring-loaded mechanism between them, move along on an air track at constant speed. The carts have different inertia, and the heavier cart is in front of the lighter cart. Then the mechanism is released, after which the speeds of the carts relative to each other is four times their original speed relative to the ground. In what direction is the lighter cart moving after the mechanism is released?

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=β2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
