How to solve numericals in physics?

Students have lots of issues in academics because they have many burdens of academics and it is very important for them. They never skip any work because If they skip any work so teachers give them bad remarks in the work so therefore every student do the hard work to getting good remarks. Well, nowadays many medical students are very troubled about the subject of Physics. The subject is very hectic, boring, and time-consuming. Mostly students face issues in numerical because it is very technical and it need the best skills that do not have with every student. Some of the students also take online help with experts where every student hires to write my assignment at cheap price. But, every time they do not afford them and now they want to get perfect solutions. They want that somebody provides the numerical tips that how to solve physics numerical.

A bullet of mass 10g travelling horizontally with a velocity of 300 m/s strikes a block of wood of mass 290 g which rests on a rough horizontal floor. After impact the block and the bullet move together and come to rest when the block has travelled a distance of 15 m. The coefficient of friction between the block and the floor will be - (Duration of impact is very short)
