Question

Find h , the maximum height attained by the projectile. express the maximum height in terms of v 0 , θ , and g .

Answer 1

the utmost height would be comprehensive while y'(t)=0. (on the suitable of the trajectory, the y speed is 0.)
`y(t)=(88sin20)t-16t^2 y'(t)=88sin20-32t So y'(t)=0 while t=(88sin20)/32`
