Question

The jet has a speed of 1260 km/hkm/h when it is flying horizontally. Air enters the intake scoop S� at the rate of 52 m3/sm3/s. The engine burns fuel at the rate of 1.85 kg/skg/s, and the gas (air and fuel) is exhausted relative to the plane with a speed of 2330 km/hkm/h. The plane has a mass of 8 MgMg. Assume that the air has a constant density of ρa�� = 1.112 kg/m3kg/m3. (Figure 1)

 

Determine the drag exerted on the plane by air resistance.
Express your answer to three significant figures and include the appropriate units.

**Jet Details:**

The jet has a speed of **1260 km/h** when it is flying horizontally. Air enters the intake scoop **S** at the rate of **52 m³/s**. The engine burns fuel at the rate of **1.85 kg/s**, and the gas (air and fuel) is exhausted relative to the plane with a speed of **2330 km/h**. The plane has a mass of **8 Mg**. Assume that the air has a constant density of \( \rho_a = 1.112 \, \text{kg/m}^3 \). ([Figure 1](#))

**Figure Description:** 

The figure shows a side view of a jet in flight with a labeled intake scoop, marked as **S**, towards the front of the jet.

**Problem Statement: Part A**

Determine the drag exerted on the plane by air resistance. Express your answer to three significant figures and include the appropriate units.
