The height of the 3 kg object can be determined using the formula for gravitational potential energy: Potential energy = mass x gravity x height. Given that the potential energy is 300 J and the mass is 3 kg, the height can be calculated by rearranging the formula as: Height = potential energy / (mass x gravity). Assuming gravity is approximately 9.81 m/s^2, the object would be approximately 9.71 meters high.
The height can be calculated using the potential energy formula PE = mgh, where m is the mass (3 kg), g is the acceleration due to gravity (~9.8 m/s^2), and h is the height. Rearranging the formula, h = PE / (mg). Plugging in the values, h = 300 J / (3 kg * 9.8 m/s^2) ≈ 10 meters.
To calculate the speed of the object, you can use the formula for kinetic energy: KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the speed. Rearrange the formula to solve for v: v = sqrt(2 * KE / m). Plugging in the values given (KE = 300 J and m = 0.05 kg) will give you the speed of the object.
The potential energy of the rock can be calculated using the formula: potential energy = mass × gravity × height. Given the mass of the rock (10.2 kg), the height of the hill (300 meters), and the acceleration due to gravity (approximately 9.81 m/s^2), the potential energy would be 10.2 kg × 9.81 m/s^2 × 300 m = 29970.6 Joules.
To find the energy of an object using Einstein's formula (E=mc^2), first convert mass from kg to kg (1 kg = 1000 g) and light speed (c) is 3x10^8 m/s. Then, substitute the values into the formula E=mc^2 to calculate the energy. The energy of an object with a mass of 300 kg would be E = 300 kg x (3 x 10^8 m/s)^2.
