The force is gravitational because when something is falling is call gravitational
Answer:
Earth's gravity comes from all its mass. All its mass makes a consolidated gravitational draw on all the mass in your body.
Explanation:
Answer:
Scale reading for no wind 
Explanation:
From the question we are told that
Area 
Weight of board 
Velocity 
Density of air 
Generally the equation for pressure difference by Bernoulli equation is mathematically given by
Generally force acting on the board by air is mathematically given by
Therefore
Scale reading for no wind W'
Scale reading for no wind W'=60N
The horse's position on the ground at time <em>t</em> is
<em>x</em> = (20 m/s) <em>t</em>
The baboon's height from the ground at time <em>t</em> is
<em>y</em> = 3 m - 1/2 <em>g</em> <em>t</em>²
where <em>g</em> = 9.80 m/s² is the magnitude of the acceleration due to gravity.
The baboon falls and lands on the horse, so that the two animals meet when the baboon's height is 2 m from the ground, which happens after
2 m = 3 m - 1/2 <em>g</em> <em>t</em>²
1/2 <em>g</em> <em>t</em>² = 1 m
<em>t</em>² = (2 m) / (9.80 m/s²)
<em>t</em> ≈ 0.452 s
In this time, the horse reaches the tree, so its distance from it is
(20 m/s) * (0.452 s) ≈ 9.04 m
