@Vinod.
May I know why didn't you put the value of acceleration while using 2nd law of motion equation.

Given data-
velocity (v) = 600km/h = (600x1000)/3600.
v = 166.66m/s.
Height (h) = 1960m.
We know that, the second law of motion.
s = ut + 0.5 * a *t * t----> 1
Put the given values in equation (1)
1960 = (0xt)+(0.5xtxt).
t(square) = 1960/0.5
t = 20 sec.
But again we know that velocity = distance/time.
v = d/t,
d = (v) * (t),
d = 20 * 166.66,
d = 3333.2m,
d = 3333.2/1000 = 3.33 km.
Ans. (d) = 3.33 km.

How to find out the angle that bomb is making with vertical?

Everybody knows oil prices increase day to day because there is a big problem in our society. In our daily life, it is the very important thing. I also think it is time to look at the green resource of energy rather than the depending upon petroleum products. In this way, our country does not make the smart country.

Projectile motion means a particle moves along curved path due to gravity and formula is 1/2gt^2.

The required distance from A to B is equal to range AB?
Please clarify it.

Mass and shape of bomb also matters. Is it true?

When body travels under the effect of gravity and when initial velocity g are not at 180 to each other i.e opposite then projectile motion in which the body follows a curved path.

Why is initial velocity not 600?
