Question
Q.#.01:Find the force required to give a block weighting 12lbs,an acceleration 8ft/sec^2.
Q.#.02:A body of mass 2kg rolling on a rough plane without any force acting on it.If it stated with the velocity of 12m/sec,and stopped after travelling 15m,find the force of friction acting the body.
note:please describe the question in details.

This sounds too much like a homework. Therefore, I'll be short.
A#1. F = m.a = 96 lb.ft/sec^2 (I leave the SI unit conversion to you)
A#2. Contradictory question. You cannot have a system in motion "without any force acting on it" and at the same time the system is decellerating and they ask for some "friction force". Either there is a force or there is not any, nothing in between is possible.

Expertise
Questions anyone (teenager, undergrad, graduate, professional) may ask on physics, mathematics or inorganic chemistry. Questions may concern subjects themselves or a possible future career in them, if you need advice on a school or hobby project, or you just came across a question that is beyond your current curriculum. I answer bare textbook problems sometimes, but I reserve the the right to redirect you to Physics-Physics section. The kind of questions I like to answer: I just started having science classes at school and they seem difficult, but I enjoy them. Where do I find more information on this, which is not in textbooks but still comprehensible to me? Just leaving high school, and I feel science is really the thing for me. Can you recommend a school and an undergrad program suitable to my inclinations? I am in my second undergraduate year in Physics. We learned the basics of universe expanding this year, the Hubble constant and all that, but invited speakers that gave talks on astrophysics in our department seemed not to agree with this model at all. Is it of any use at all? I am building a [materials research] experimental device for my masters/doctorate thesis and I have the following problem:... I have tried ..., but it still doesn't work. Where might the problem be?
