I was wondering if someone could check my work and see if its correct.(adsbygoogle = window.adsbygoogle || []).push({});

An object of mass 100.00kg moves in a straight line under the influence of a force given by F(t)=(120 N/s)t+4000N

At t=0 it is moving at 0 m/s. Determine its speed at t=5.00 s

What i did is this. I plugged 5s into the function and got 4600N. Then i used F▲V=M▲V arranged to V=(F▲T)/M

V=(4600N X 5.00s)/100.0kg

V=230. M/S

Thank you
