PROJECTILE MOTION PART 1

-
Projectile is the name given to a body which, after having been given an initial velocity, is allowed to move under the influence of gravity alone.

 A body projected horizontally with a velocity u from a height h



Horizontal and vertical distances covered in time t are















    Differentiating above equations with respect to time t, we get the horizontal and vertical velocities















    Equation of trajectory








    Time of flight 












    Horizontal range










    Magnitude of resultant velocity at time t 








    The angle α which the resultant velocity vector subtends with the vertical is given by

    Here we would solve a dot puzzle Consider the figure below Connect all the dots without lifting the pen with only 4 straight lines and the lines do not overlap. Here are some examples already done for you but not been solved because some dots left to be crossed. You could see that some dots have been left to be crossed by the line. So do you think you could solve it. Let us try one more time. Now, what do you see, the puzzle has been solved with the required conditions. Find out some more solutions to this question.

    EULER TRAIL PUZZLE

    -

    What is an Euler trail ? An Euler trail ( Euler path ) is a trail in a finite graph which visits every edge exactly once. An Euler trail is a walk on the edges of a graph which uses each edge exactly once. Euler trail is also called an Euler chain , Euler walk , Euler path . Here is the puzzle as you could see in the picture. Your job is to cross each line exactly once without lifting your pen.  In the following figure consider every marked line as a single line and each must be crossed once without lifting you pen. Here are some examples already done, but in each case, one line is left ( marked red ) to be crossed . See the figures. Have you got the solution ? well, this is impossible to do however hard you try.  Explanation Consider the figure below and find the numbers of line reaching the centre of each box. In the figure you could see that there are three centre points with odd number of lines
