A block rests on a frictionless table on Earth. After a 20N 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?

Best ResponseYou've already chosen the best response.0Since the force is horizontal, and the table is 'frictionless' then the weight of the object does not affect its acceleration. Since the applied force on the moon is half that applied on earth (10N as compared with 20N) then the acceleration horizontally should also be half 3.9/2 = 1.95m/s That is not one of your options I see  maybe for some reason they have rounded it to 2, but that doesn't make sense as they may as well have said it was 4 on earth! I think the correct answer is 1.95m/s^2 (NOTE  I do NOT normally give answers  but since this seems to have a problem I thought I'd discuss it her.)
