WebApr 6, 2024 · A. The kinetic energy of B is 4 times that of A. B. The kinetic energy of B is twice that of A. C. The kinetic energy of A is the same as that. A 5.36 kg object falls freely (ignore air resistance), after being dropped from rest. Determine the initial kinetic energy, the final kinetic energy, and the change in kinetic energy for the following. WebApr 27, 2015 · The initial potential energy plus the initial kinetic energy plus the work done on the system is equal to the final kinetic energy plus the final potential energy. KE i + PE i + W ext = KE f + PE f In this problem we're assuming that the initial velocity (speed at the top of the first hill) is zero, so KE i =(1/2)m(v i ) 2 =0.

WebLoss of Kinetic Energy During Collision: Enter the Initial Velocity of Body 1 (u 1) : Enter the Initial Velocity of Body 2 (u 2) : Enter the Mass of Body 1 (m 1) : Enter the Mass of Body 2 (m 2) : Enter the Coefficient of Restitution (e) : Switches: Mathematics: Physics: Gas Laws: … WebWhat is its kinetic energy. Answer: Kinetic energy is the energy an object possesses due to its motion, and is given by the formula: Kinetic energy = 1/2 * mass * velocity^2. To find the kinetic energy of the 11 kg object moving at 6.4 m/s, we can plug in the values into the formula: Kinetic energy = 1/2 * 11 kg * (6.4 m/s)^2. Kinetic energy ... WebFeb 17, 2024 · Explanation: K.E = 1 2 ⋅ m⋅ v2. m is the mass. v is the velocity. m = 6. v = 4. ∴ K.E = 1 2 ⋅ 6 ⋅ 42 = 48J. ∴ 48 joules. Answer link. how many aboriginal people died
