for science what is the kenitic energy of a 150 kg object that is moving with a speed of 15 m/s. 2.if a an object with a mass of 10 kg is moving at a velocity of 5 meters per second what would be the kinetic energy of an object.
Answer (1)
1. Kinetic Energy of a 150 kg object moving at 15 m/s - Formula: Kinetic Energy (KE) = 1/2 * mass * velocity²- Plug in the values: KE = 1/2 * 150 kg * (15 m/s)²- Calculate: KE = 75 kg * 225 m²/s²- Result: KE = 16,875 Joules (J) Therefore, the kinetic energy of the 150 kg object is 16,875 Joules. 2. Kinetic Energy of a 10 kg object moving at 5 m/s - Formula: KE = 1/2 * mass * velocity²- Plug in the values: KE = 1/2 * 10 kg * (5 m/s)²- Calculate: KE = 5 kg * 25 m²/s²- Result: KE = 125 Joules (J) Therefore, the kinetic energy of the 10 kg object is 125 Joules.
