i am currently momentum, work, energy and power in physics and i am currently confused in a few concepts.
This question states that:
A car with mass 1500kg accelerates from 0 to 100km/hr in 4 seconds. calculate the power output of the car.
-- My teacher states to solve this question using kinetic Energy = Work , and equating this into the power formula...
is there a reason why you have to use this approach to solve the question?
when i try and figure it out , i use momentum and impact and i get a completely different answer.
The thing i struggle with is if i get given a question, which method do i use to solve it??
thankyou
