The speed of the starling is 36 km / h, its mass is 100 g, it flies across the sky at an altitude of 50 m.

The speed of the starling is 36 km / h, its mass is 100 g, it flies across the sky at an altitude of 50 m. Find the total energy (En + Ek)

Initial data: V (starling speed) = 36 km / h (10 m / s); m (starling weight) = 100 g (0.1 kg); h (height at which the starling flies) = 50 m.

Constants: g (acceleration due to gravity) ≈ 10 m / s2.

The total energy of a starling can be calculated by the formula: E = En + Ek = m * g * h + 0.5 * m * V ^ 2 = m * (g * h + 0.5 * V ^ 2).

Let’s make a calculation: E = 0.1 * (10 * 50 + 0.5 * 10 ^ 2) = 55 J.

Answer: The total energy of a starling is 55 J.
