A block rests on a frictionless table on Earth. After a 20-N horizontal force is applied to the block, it accelerates at 3.9 m/s2. Then the block and table are carried to the moon, where the acceleration due to gravity is 1.62 m/s2. A horizontal force of 10 N is then applied to the block. What is the acceleration?
