Physics

Acceleration is a vector, meaning each acceleration has both magnitude and direction. The resultant of vectors is basically the net acceleration on the object expressed as a single vector. For example, if there are two vectors each with a magnitude of 2 meters/(seconds squared) acting on an object and these vectors were placed on the x and y axes then you could represent this system of 2 vectors 90 degrees apart each with a magnitude of two meters/(seconds squared) as one vector of 45 degrees with a magnitude of 2 times the square root of 2 meters/(seconds squared).

No it is not bad, as some ladies have a heavy period for one month and then a light one or they may have two heavy periods and then one light one also.

yes and that is 9.8m/s2

The total displacement will be calculated using Pythagoras theorem. The distance traveled will form the two sides of the triangle. Hence we have to calculate the hypotenuse side using the formula Square root of (2 power 2 + 1 power 2)=Square root(5)=2.23
