Answer:
The value is
Explanation:
From the question we are told that
The distance of the target from the riffle is
The height at which the bullet hit the target is
Considering the vertical motion
Generally from kinematic equations we have that
At the initial stage the velocity is zero i.e
=>
=>
Generally the velocity of the bullet when it leaves the riffle is mathematically represented as
=>
=>
We have that the initial velocity is mathematically given as
V1=86.4m/s
<h3>Velocity</h3>
Question Parameters:
- A 0.05 kg arrow
- Is fired at a velocity towards a 1.2 kg apple.
- The arrow sticks in the apple and both move at 3.6m/s.
Generally the equation for the Conservation of momentum is mathematically given as
M1V1=M2V2
Therefore
0.05*V1=1.2*3.6
V1=(1.2*3.6)/0.05
V1=86.4m/s

Normal force is the force exerted when an object is on an surface. So an example could be a pile of books on top of a table.
Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too:
[ Protractor can be use only in real life, not here ]
Draw an imaginary line from initial position to final position.
Now, In that triangle, tan x = P/B
tan x = 1.4 / 2
tan x = 0.70
x = tan⁻¹ (0.70)
x = 35 [ tan 35 = 0.70 ]
In short, Your Answer would be 35 degrees
Hope this helps!
