1. The problem statement, all variables and given/known data Mike is dragging a 20.0 kg crate across the floor. If he exerts 40 N force upon the crate and there is a 25 N frictional force opposing the crate's motion, how fast will the crate be moving after 2.0 seconds if it is initially at rest? 2. Relevant equations FNET=ma 3. The attempt at a solution I used FNET=ma to solve for the acceleration as follows: FPC-FFC=ma 40-25=20a 15=20a a=0.75m/s2 Then here's where I'm not sure if this is correct: I multiplied the acceleration 0.75m/s2 by 2.0 seconds to get 1.5m/s2. Is this the correct answer for the question: How fast will the crate be moving after 2.0 seconds? Thanks.
