I'm new to physics, and would like a little help in solving this problem. I am in a problem with Newton's second law...the formula is Force = Mass times Acceleration. The problem states: A truck produces a force of 100 N as it accelerates from 5 m s to 10 m s in 5 seconds. What is the Mass of the truck, and what is the weight of the truck? I can't seem to understand how to find the acceleration and the weight. Can someone help me? thanks!
