I have another question for u guys could u plz help me out? so here it is? Anthony threw a ball from the top of a 10-story building that was 165 feet tall. The equation g(165-h)=1/2v^2 can be used to find the maximum height the ball can attain after being thrown from the top of the building. In this equation g represents the acceleration due to gravity (32 feet per second squared), h is the maximum height attained by the ball, and v is the speed of the ball. rewrite the equation to highlight the maximum height attained by the ball, h.
