79.
An aeroplane is flying horizontally with a velocity of 600 km/h and at a height of 1960 m. When it is vertically at a point A on the ground a bomb is released from it. The bomb strikes the ground at point B. The distance AB is
1200 m
0.33 km
3.33 km
33 km

Velocity:600*5/18 m./sec.=500/3m./sec. Hy=Uy*t+1/2g*t*t : 1960=0+ 1/2*9.8*t*t therefore t=20 sec. So Range AB=v*t=500/3*20 m.=10/3 km.=3.33 km.

When a body is projected into space and no longer propelled by fuel and other external forces except gravity it's motion is called a projectile motion.

They haven't mentioned the time.

Then how did you guys calculate the projectile motion? Please explain me.

@Vinod.

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

@Tms.

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.

Actually what is this question talking about when the time is not given.

Why is initial velocity 0? Why not 600 as plane is moving at 600?

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

What is projectile motion and not sure about this question?
