SOLUTION:

Velocity = 600km/hr=600*1000/3600m/s.
= 166.66m/s.

FORMULA:

Ht = 0.5*a*t*t.
Ht = 0.5*9.8*2*2.
Ht = 19.6+0.4.
H t= 20 seconds.

R = V*t.
R = 166.66*20 SEC.

R = 333.2km.
R = 333.2/1000.
R = 3.33km.

Therefore R is 3.33km.

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.

1960/600 = 33.2666666666667.

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

Rajat shukla said:   10 years ago
Why is initial velocity not 600?

Rajat shukla said:   10 years ago
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.
