Answer:
1.38 into 10 power minus 58 Newton is the answer
Answer:
44.1613858478 m/s
Explanation:
t = Time taken
u = Initial velocity = 0
v = Final velocity
s = Displacement = 99.4
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
![v^2-u^2=2as\\\Rightarrow v=\sqrt{2as+u^2}\\\Rightarrow v=\sqrt{2\times 9.81\times 99.4+0^2}\\\Rightarrow v=44.1613858478\ m/s](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B2as%2Bu%5E2%7D%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B2%5Ctimes%209.81%5Ctimes%2099.4%2B0%5E2%7D%5C%5C%5CRightarrow%20v%3D44.1613858478%5C%20m%2Fs)
If air resistance was absent Dan Koko would strike the airbag at 44.1613858478 m/s
<h2>
It takes 6.78 seconds to complete 12 dribbles.</h2>
Explanation:
Frequency of dribble = 1.77 Hz
That is
Number of dribbles in 1 second = 1.77
![\texttt{Time taken for 1 dribble = }\frac{1}{1.77}=0.565s](https://tex.z-dn.net/?f=%5Ctexttt%7BTime%20taken%20for%201%20dribble%20%3D%20%7D%5Cfrac%7B1%7D%7B1.77%7D%3D0.565s)
Now we need to find how long does it take for you to complete 12 dribbles.
Time taken for 12 dribbles = 12 x Time taken for 1 dribble
Time taken for 12 dribbles = 12 x 0.565
Time taken for 12 dribbles = 6.78 seconds
It takes 6.78 seconds to complete 12 dribbles.
Answer: The volume is decreasing at a rate of 80 cm3/min
Explanation: Please see the attachments below
Rise over run at 1 second
It’s the same slope from 0 to 2 seconds
10/2=5mps
As a note all time points between 0and 2 will have this instantaneous velocity
Instantaneous velocity at time 2 is 0
