Im sure this is very easy but just learning V=velocity A=acceleration S=displacement t=time if V=4t+5 and S=10m when t=1s, find S when t=2s just not sure what to do :/

so by integrating i get 2t^2 + 5t ??? and does this = s/t? still a bit uncertain thankyou for helping
1 2 3 4 5 Now at t=1s s= 2 + 5 +c = 10m hence c= 3 6 Put the value of t= 2s s= 18+3 =21m Now tell the step(s) that you dont get or have a doubt in
thing is i've never really been taught what the '+C' part is just told to write it (which i forgot to do lol) but yes i understand your method thanks
