Answer:
28.2 m
Explanation:
Applying,
Pythagoras theorem,
a² = b²+c²............... Equation 1
Where a = The distance from my starting point to my current point, b = distance walked due west, c = distance walked due south
From the question,
Given: b = 13 m, c = 25 m
Substitute these values into equation 1
a² = 13²+25²
a² = 169+625
a² = 794
a = √794
a = 28.18 m
a ≈ 28.2 m
The answer is A
Hope that helps!
Answer:
F = 47261.5 N = 47.26 KN
Explanation:
First, we will calculate the deceleration of the bullet by using the third equation of motion:
where,
a = deceleration = ?
s = distace covered = 5.2 cm = 0.052 m
vf = final speed = 0 m/s
vi = initial speed = 640 m/s
Therefore,
negative sign shows deceleration.
Now for the force, we will use Newton's Second Law of Motion:
F = ma
where,
F = Force = ?
m = mass of bullet = 12 g = 0.012 kg
Therefore,
F = (0.012 kg)(3938461.5 m/s²)
<u>F = 47261.5 N = 47.26 KN</u>
Answer:
yeah this statement is tru
Explanation:
it is because the speed of the bullet is more than the speed of rolling ball .so from this reason we cannot catch a bullet.
