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

Question

Quizplus · Accepted Answer

On Earth:
F = ma
90 N = m (3.6 m/s^2)
m = 25 kg
On the moon:
F = ma
45 N = m (a)
a = 45 N / 25 kg
a = 1.8 m/s^2
