The solution would be like
this for this specific problem:
<span>v = ? </span><span>
<span>u = 0.0 m/s </span>
<span>a = 9.8 m/s^2 </span>
<span>s = 56.1 m </span></span>
<span>v^2 = (0.0 m/s)^2 + [2 *
(9.8 m/s^2) * (56 m) ] </span><span>
<span>v^2 = 2 * (9.8 m/s^2) * (56 m) </span>
<span>v^2 = 1,097.6 m^2/s^2 </span>
<span>v = SQRT {1,097.6 m^2/s^2 } </span></span>
v = 33.1 m/s
<span>v = u + at </span>
<span>(v - u) / a = t </span>
[ (33.1 m/s) - (0.0 m/s)
] / (9.8 m/s^2) = 3.38 seconds
If the pigeon is 56.0 m below the initial position of the
falcon, it will take 3.38 seconds for the falcon to reach the pigeon. I am
hoping that this answer has satisfied your query and it will be able to help
you in your endeavor, and if you would like, feel free to ask another question.
Answer:
Acceleration is the rate of change in velocity. Momentum is the mass times the velocity. So if you multiply the mass times the acceleration, you get the of change of momentum.
Answer:
1088.9N/m2
Explanation:
Calculation for What pressure is exerted
First step is to find the area of bottom of the tank using formula
Area=Width*breadth
Let plug in the formula
Area=0.5*0.9
Area=0.45m2
Now let calculate what pressure is exerted using this formula
Pressure=Force/Area
Where,
Force=Mass *Gasoline
Area=Width of the tank* Length of the tank
Let plug in the formula
Pressure=50*9.8/0.5*0.9
Pressure=490/0.45
Pressure=1088.9N/m2
Therefore What pressure is exerted is 1088.9N/m2
