Thanks for the help. These are the answers I have come to, but i am still not certain about part (a), are they correct, and if not where am I going wrong? Many Thanks again!

a) Assuming it is inelastic as it is accelerating and therefore kinetic energy is not conserved? Intuitively this doesn't feel right... b) change in momentum = p initial - p final = force x time p initial = 0 as at rest p final = 0.25 x v2 force x time = area under graph = 0.1 therefore 0.25 x...
