Best ResponseYou've already chosen the best response.0Slope of tangent of velocitytime graph gives accelaration. V at any instant 't' = dv/dt at 't' Hope you know what to do next.

Best ResponseYou've already chosen the best response.0Hi first you ought find V equation & differentiate from it proportion t to reaching acceleration equation in general V is\[V=bt ^{2}+ct+V _{0}\] we know v0=4 if you differentiate from V yields\[a=2bt+c\] in t=0 a=0 so reaches c=0 now V equation is\[V=bt ^{2}+4\] from graph we can find b so b=.222222222222222222222 finally V is:\[0.22222222t ^{2}+4\] differentiate proportion t from above & find acceleration on t=3 i find 1.3
