If a question asks to calculate total energy of an object that does have a horizontal velocity (constant, air resistance ignored), and it is at it's highest point so it's vertical velocity is zero.
I need to know how you'd calculate the total energy of this object.
Let's take mass as 5kg. And a highest point of 3m. Horizontal velocity of 2m/s. (I just made them up).
Potential energy = mgΔh
Kinetic energy = 0.5mv^2
The Attempt at a Solution
Pe= 5*9.81*3 = 147.15J
Ke= 5*2^2= 20/2 = 10J
I was just wondering if I am not leaving anything out, or if I'm even doing it correct! Thanks
