Circle = perpendicular cross section of a cylinder
cone = perpendicular cross section of a pyramid
3 quarters and a dime a nickel and 4 pennies

Let's solve ~




It's factorized now ~ And if you want to find the zeros then equate the expression with 0.
And you will get ;

The formula is K = v^2 /2
You are told K = 32.
Replace K and solve for v:
32 = v^2 / 2
Multiply each side by 2:
64 = v^2
Take the square root of both sides:
v = √64
v = 8 meters per second.
