Answer:
It slowly decreases and the friction acting on it slowing it down becomes the bigger net force, if that makes sense :)

Explanation:
Answer: Gamma rays
Gamma rays have the highest frequency.
What is an electromagnetic wave?
An electromagnetic wave requires no medium for its propagation.
It consists of a spectrum of different wavelengths.
Different wavelengths of rays have different energies and different frequencies.
Higher frequency rays have the highest energies.
What is gamma-ray?
These are ionized radiations.
Gamma radiations are obtained from the decay of the atomic nucleus.
It has the highest frequency which is why it can penetrate through matter.
It has the smallest wavelength and highest energy.
The frequency of gamma rays is more than 10^19 cycles per second and wavelength less than 100 picometers.
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.
