Answer:
7.22×10¹⁰ J
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 7.6 Km/s
Mass (m) = 2500 kg
Energy (E) =?
Next, we shall convert 7.6 Km/s to m/s. This can be obtained as follow:
1 km/s = 10³ m/s
Therefore,
7.6 Km/s = 7.6 Km/s × 10³ m/s / 1 km/s
7.6 Km/s = 7.6×10³ m/s
Finally, we shall determine the energy required as follow:
Velocity (v) = 7.6×10³ m/s
Mass (m) = 2500 kg
Energy (E) =?
E = ½mv²
E = ½ × 2500 × (7.6×10³)²
E = 1250 × 57760000
E = 7.22×10¹⁰ J
Thus, 7.22×10¹⁰ J of energy is required.
