Newton's Second Law in 1 Dimension: A block is on a frictionless table, on earth. The block accelerates at 5.3 m/s2 when a 10 N horizontal force is applied to it. The block and table are set up on the Moon where the acceleration due to gravity is 1.62 m/s2. A horizontal force of 5 N is now applied to the block when it is on the Moon. The acceleration imparted to the block by this force is closest to
A. 2.7 m/s2.
B. 2.4 m/s2.
C. 2.9 m/s2.
D. 3.2 m/s2.
E. 3.4 m/s2.
