That make sense Thank you!

Thanks PeroK and PSN03 I think I got it! So the impulse is calculated from force applied, which is 75 N (area under the graph). So for 10 s we have J = F*t = 75 N*10 s = 75 N s So we have J = pf-pi 75 N = 10 kg*v -> v = 7,5 m/s So the final velocity after 10 s is 10 + 7,5 = 17,5 m/s It...

I think I maybe haven't explained myself correctly I want to find the velocity of the object to t = 10 s When I have the force applied to the object over time, I can calculate the acceleration from F = ma, so I get a = 1 m/s^2 for t = 0 to t = 5 a = 0,8 m/s^2 for t = 6 a = 0,6 m/s^2 for t = 4...

I meant that the graph would be 20-2t for t = 5 to 5 = 10 s But integrated the graph is 20t - t^2 But I think I am doing something wrong before this

Sorry my mistake I meant t instead of x

Thank you :smile:

I have some troubles with this relatively simple problem My idea was to find the acceleration by F = ma and then integrate the graph and then find the velocity to t = 10 s + start velocity The graph will be - 2x And integrated -x¨^2 But this seems wrong Thanks in regards

Hope to get some help with my daily homework.But I cannot figure out, where to post questions.Thanks in regards.
