A ball is rolled over a level lawn with initial velocity 8ms^1. due to the friction the velocity decreases and is given by dv/dt=2. Find the equation of distance travelled?

Best ResponseYou've already chosen the best response.0First integrate dv/dt =2 so it becomes v = 2t +C, at t =0, v=8, plug in, find C then that's the equation of velocity. then integrate velocity equation

Best ResponseYou've already chosen the best response.0so, what the meaning of equation of distance travelled? add the equation we get or what?

Best ResponseYou've already chosen the best response.0it's the equation of distance travel in term of t, like s(t)= ...., and when you integrate velocity equation, you get distance equation

Best ResponseYou've already chosen the best response.0So, s(t) = t^2 +8t +C

Best ResponseYou've already chosen the best response.0And I think at time t=0, the distance travel is 0, so 0= 0+0 +C, so C=0 s(t) = t^2 +8t is distance equation

Best ResponseYou've already chosen the best response.0why we must integrate the velocity equation again?

Best ResponseYou've already chosen the best response.0At first, you're given dv/dt, which is the derivative of velocity, or acceleration. After you integrate it, it becomes velocity equation, which is v(t) = 2t +8. THen you integrate again to get position equation or distance travel.
