A worker drives a 0. 500 kg spike into a rail tie with a 2. 50 kg sledgehammer. The hammer hits the spike with a speed of 65. 0 m/s. If one-third of the hammer’s kinetic energy is converted to the internal energy of the hammer and spike, how much does the total internal energy increase?.

the answer is:

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !
