Answer:
E =16.82 joules
Step-by-step explanation:
so this is a basic substitution problem. 0.145=m and 40=v. So, 1/2(.145)(40)^2. That is the equation. Now you solve. remember PEMDAS. So, its .145x40= 5.8 then square 5.8= 33.64 then multiply 33.64 by 1/2 which is equal to 16.82 so your answer is E=16.82 joules.
