Question

A bullet fired from a gun with a velocity of 140 ms-1
strikes the ground at the same level as the gun at a
distance of 1 km. Find the angle, with the ground, at
which the gun is fired. g = 9.8
​

Answer 1

Answer:

we know, u = 140 m/s and r = 1000m

r = u^2 sin2theta / g

so 1000= 140 ×140 sin2theta / 10

sin 2theta = 1000/1960

So 2 theta = 30.7 °

theta = 15.35° ans
