relation between F(n) and t grpah to acceleration and velocity
ermm.. so the force time graph is given to you and you are asked to find what is the acceleration and velocity?!
well.. you need to know what is the mass.. else you couldn't find acceleration :-/
then at t = 2s you know what is the force .. can be obtained from the graph right??
f=ma so 4=(3)a and a=4/3
