Given
Initial velocity:
36 ft/s
Initial height:
0 ft
Vertical motion model:
h(t) = -16t^2 + ut + s
v = initial velocity
s = is the height
Procedure
We are going to use the model provided for the vertical motion.
We know that at the maximum height the final velocity is 0.
Then we will use the following expression to calculate the maximum height:
Now for time:
Solving for t,
The total time the kangaroo takes in the air is 2.3s.

<h3 /><h3>What is hydrogen bonding?</h3>A hydrogen bond is an attraction between an electronegative atom carrying a single pair of electrons—the hydrogen bond acceptor—and a hydrogen atom that is covalently bonded to a more electronegative "donor" atom or group.
One definition of a polar covalent bond is one in which one atom has a stronger alternation for electron negativity difference between two bonds, the more polar the link.
Polar molecules like H2O have a mild partial negative charge in one area and a partial positive charge in another.
