12. A physics student makes a device that prevents an egg from cracking when dropped. The mass of the device with the egg inside is 0.5 kg. The device is dropped and hits the ground with a velocity of 5 m/s. If 15 N of force is applied to the egg, how long did it take for the velocity to reach zero?
