If X-axis is taken vertically, Z-axis towards north and Y-axis along east, then the velocity of the bullet is v = 500 km/sec. and angular velocity - UTP2  because the angular velocity vector ww of the earth is directed parallel to its axis and is inclined at 300 to the horizibtal.

Hence coriolis acceleration

Coriolis Effect

The Coriolis effect is the apparent deflection of the path of a moving object caused by the rotation of the Earth. It is an important concept in physics and is particularly relevant in the case of projectiles or objects moving long distances.

Given:
Mass of the bullet, m = 10 gm = 0.01 kg
Velocity of the bullet, v = 500 m/s
Latitude, θ = 300N
Distance traveled, d = 250 m

Now let's analyze the given statements one by one.

a) The Coriolis acceleration is 0.036 m/s² towards the west.

The Coriolis acceleration, aC, can be calculated using the formula:
aC = 2 * v * ω * sin(θ)

where ω is the angular velocity of the Earth, given by:
ω = 2π / T

T is the period of rotation of the Earth, which is approximately 24 hours or 86400 seconds.

Substituting the given values, we can calculate the Coriolis acceleration:
ω = 2π / 86400 s ≈ 7.27 × 10⁻⁵ rad/s
θ = 30° = π / 6 rad

aC = 2 * 500 m/s * 7.27 × 10⁻⁵ rad/s * sin(π / 6) ≈ 0.036 m/s²

Therefore, the statement is correct.

b) The time of journey, t = 0.5 sec.

The time of journey can be calculated using the formula:
t = d / v

Substituting the given values, we get:
t = 250 m / 500 m/s = 0.5 sec

Therefore, the statement is correct.

c) The deflection of the bullet due to the Coriolis acceleration is 4.5 × 10⁻³ m.

The deflection of the bullet, Δx, can be calculated using the formula:
Δx = (1/2) * aC * t²

Substituting the given values, we get:
Δx = (1/2) * 0.036 m/s² * (0.5 sec)² ≈ 4.5 × 10⁻³ m

Therefore, the statement is correct.

d) The vertical displacement of the bullet due to gravity is 1.23 m.

The vertical displacement of the bullet, Δy, due to gravity can be calculated using the formula:
Δy = (1/2) * g * t²

where g is the acceleration due to gravity, approximately 9.8 m/s².

Substituting the given values, we get:
Δy = (1/2) * 9.8 m/s² * (0.5 sec)² ≈ 1.23 m

Therefore, the statement is correct.

In conclusion, all the given statements are correct.
