acceleration and net force?

Question

Two students are in the library sitting across the table from each other. One student takes a book with a mass of 1.65 kg and pushes it across the table with a net force of 6 N. What is the acceleration of the book?

Answer 1

Start with Newton's second Law, F=ma

Here, F = 6 N, m = 1.65 kg, so a = F/m = 6N/1.65 kg = 3.64m/sec/sec

Answer 2

Newton's Second Law

F = ma

where F is the net force, m the mass, and a the acceleration. Plug in the given net force and mass and solve for acceleration.
