Answer:

Explanation:
Given that,
Initial angular velocity, 
Final angular speed, 
Angular displacement, 
We need to find the angular acceleration of the tire. We can find it using the third equation of rotational kinematics. So,

So, the angular acceleration of the tire is equal to
.
Answer:A) noble gases
Explanation: key word gas. if you fart it smells and other gases harm.

The equation is h(t) = at^2 + vt + d
where a = acceleration of gravity = - 32.174 ft/sec^2
v = 25 feet/sec
d = starting height = 0
and h(t) = 0 when the ball hits the ground.
So, 0 = - 32.174t^2 + 25t + 0
You can use the quadratic formula on that if you want, or you can solve like this:
0 = - 32.174t^2 + 25t
0 = t ( -32.174t + 25)
So, one solution of that is t = 0, corresponding to the initial time when the ball is kicked.
The other time is: 25 = 32.174t
t = 25/32.174 = 0.777 seconds
or approximately 0.8 seconds.</span>
