TRAJECTORY (PATH) OF PROJECTILE Along y- axis  using  Along x-axis using      By this equation it can be prove that path of projectile is parabola

OTHER FORMA OF EQUATION OF TRAJECTORY      Projectile Motion when initial point and final point are at different level

Case I Horizontal projection from certain height Here angle of projection q = 0˚

In vertical Mirror Using    Time to strike ground in horizontal Mirror

IN HORIZONTAL MIRROR =   Example: Which ball will strike the ground first

(a) Ball A          (c) Ball C

(b) Ball B         (d) All Balls will strike simultaneously Solution   There fore all three Balls strike the ground simultaneously                      Answer (d)

Example: A jet fighter plane is flying at constant speed of 360 km/h and jet plane is moving horizontally at a height of 20 km from earth ‘s surface. Jet release a bomb to hit  a target on the ground, how much horizontal gap before jet will release the bomb Solution

As discussed above using    Example: A stair case having each step 10 cm high and 20 cm wide.

If a ball drops in horizontal direction from the top step with 10 mt/sec

in horizontal direction If ball strikes nth step of staire case find the n? Solution     Now make a twist in above question

Every  data is same except velocity of ball, if initial velocity not given , and saying what will be minimum initial velocity in above question so that ball hits 50th step Solution

Now x = 49 x 0.2 mt

h = 49 x 0.1 mt   Join any of the batches using this book
