The image below "gives, as a function of time t, the force component x that acts on a 2.40 kg ice block that can move only along the x axis. At t = 0, the block is moving in the positive direction of the axis, with a speed of 2.5 m/s. What is its velocity, including sign, at t = 11 s? Answer: 8.8 m/s" Relevant equations: F=ma Vf = Vo + at I was thinking that the total area under the graph would give the net force the component seeing that the y-axis represents Force and the x-axis represents Time. With that I got the net force 15N (29N - 14N). So, F = 25N F = ma m = 2.40kg Vo = 2.5m/s t = 11 Vf = ? Therefore, with the given information, I decided to use the following kinematic equation to find acceleration. Vf = Vo +at a = (Vf - Vo)/t So, F = m(Vf - Vo)/t And if we solve for Vf we get Vf = tF/m + Vo ____________________________________________________________ However, when I plug in the units I get an answer that is way way off. Vf = 11(15)/2.4 + 2.5 Vf = 165/2.4 + 2.5 Vf = 68.75 + 2.5 Vf = 71.25 m/s I know I added in the units at the end but I checked and the units come out correctly. Therefore, my question is: what did I do wrong? Why am I so far off? Obviously I did something horribly wrong in my calculation, but where? Thank you for taking the time review my question. Any help is much appreciated.
