Answer:
Explanation:
m = Mass of ball = 150 g
= Angle of kick = 
= Displacement of ball in x direction = 12 m
Range of projectile is given by
The velocity of the ball instantly after the man kicks the ball is
Impulse is given by
The impulse of his foot on the ball is .
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.
The work done is calculated by multiplying the Force by the distance. So, 10x20 = 200 joules.
I hope this is the answer you are looking for, if not good luck on finding your answer ;D
time to reach an angular velocity of 36.8 is 24.370 s.
<h3>
</h3><h3>What is angular acceleration?</h3>
The temporal rate at which angular velocity changes is referred to as angular acceleration. Naturally, there are two forms of angular acceleration, referred to as spin angular acceleration and orbital angular acceleration, just as there are two types of angular velocity, namely spin angular velocity and orbital angular velocity. As opposed to orbital angular acceleration, which is the angular acceleration of a point particle around a fixed origin, spin angular acceleration describes the angular acceleration of a rigid body about its centre of rotation.
w(t) = w(0) + α*t
also w(0) =0
=> time = 36.8/1.51= 24.370 s
