Equation for finding kinetic energy
WebApr 7, 2024 · Solution. Earth’s radius = 6.37 × 106 m. Mass of Earth = 5.97 × 1024 kg. We need to first find the moment of inertia to calculate rotational kinetic energy. Considering the shape of the Earth as a sphere we get: Moment of inertia I of Earth = ⅖ * m * r2 = ⅖ * (5.97 × 1024 kg * (6.37 × 106 m)2) = 9.69 * 1037 Kg.m2. WebBecause the mass m and speed v are given, the kinetic energy can be calculated from its definition as given in the equation KE = 1 2 mv 2. Solution The kinetic energy is given by KE = 1 2 mv 2. 7.13 Entering known values gives KE = 0. 5 ( 30.0 kg) ( 0.500 m/s) 2, 7.14 which yields KE = 3.75 kg ⋅ m 2 /s 2 = 3.75 J. 7.15 Discussion
