A projectile of mass 20 kg is shot at an angle of 60 degrees to the horizontal at a speed of 100 m/s. What is the energy of the projectile at its highest point?
Answer: 1 x 10^5 J
They explain the answer using the KE equation. I am just confused as to how KE is used since I thought speed at the highest point or max height is 0. Thus KE=0. Am I missing something here? Thank you in advance.
