Darlene kicks a soccer ball off the ground and in the air with an initial velocity of 34 feet per second. using the formula h(t) = _16t2 + vt + s, what is the maximum height the soccer ball reaches?
17.7 feet
18.1 feet
19.3 feet
20.2 feet

At maximum height, the velocity of the ball is 0.
v = u + at
0 = 34 - 32.2t
t = 1.06 seconds

In H(t), s = 0 because the ball is initially on the ground.

H(t) = -16(1.06)² + 34(1.06)
H(t) = 18.1 feet

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
