Question Answered step-by-step GRADE 11 PHYSICS I have two Mechanical Energy questions that I am… GRADE 11 PHYSICSI have two Mechanical Energy questions that I am stuck on. 1) In the attachment below, the first page is the explanation we were given about kinetic energy. Then, there is the practice 4 question that has been highlighted. In the question, there is a hint given, in I don’t understand. The second attachment underneath this is the answer to the practice question. The thing I don’t understand is where the 27J has come from. It is supposed to be the energy that will increase the speed of the vehicle, but when I attempt to solve for the same number (27J) using the Ek=1/2(mv^2) formula, I do not get that number. Even though the question is not asking for it, where is this number coming from?
