Answer #1

Fair Fair= kv5v

a(t)(t) is acceleration then F=ma=--5u (as it is a resistive force) and v(0)=43

So 1 380 5 76 380 LO (ignoring any gravity effects)

Meaning In(u) In(C) (t) Cexp 76 76

And intial condition implies t v(t) 43 exp 76 is the required velocity as a function of time

t = / v(t) dt = D - 76 x 43 exp ( s(t) 76 r

t s(t)D 3268 exp 76 with s(0)O

So we have

t s(t) 3268 3268 exp 76

Meaning the furthest distance it can get to is {\color{Red} 3268} meters
