A Block Is on a Frictionless Horizontal Table, on Earth

question 25

Multiple Choice

A block is on a frictionless horizontal table, on earth. This block accelerates at 3.6 m/s² when a 90 N horizontal force is applied to it. The block and table are then set up on the moon where the acceleration due to gravity is 1.62 m/ s². A horizontal force of 45 N is applied to the block when it is on the moon. What acceleration does this force impart to the block?

• A) 1.8 m/s²
• B) 1.6 m/s²
• C) 2.0 m/s²
• D) 2.2 m/s²
• E) 2.3 m/s²
