The reason why it relates to the newtons 3 laws of motion because the first law of motion states that every object will stay at rest unless it's moved by an unbalanced force which is your hand. The second one states that <span> the velocity of an object changes when it is subjected to an external force meaning it's used by the equation that is commonly used for which is F=M*A. The way it relates to the second law because you are adding force some way or another, the mass is the egg and the acceleration is the drop of the egg while it free falls. And the last one, for a reaction there is always an equal or opposite reaction and the opposite reaction is the floor because it's going against the egg causing it to crack. If it was with the egg, it would have a soft, smooth landing.</span>
Mass = (2*KE) / v²
∴ the answer is 200/49
Answer:
0m/s^2
Explanation:
have a beautiful day ahead
I don't know about 1 but I know you should check 2 & 3 definitely
Given Information:
Acceleration = a = 3.5×10⁵g
Gravitational constant = g = 9.8 m/s²
Distance from axis of rotation = r = 2.0 cm = 0.02 m
Required Information:
Angular speed = ω = ?
Answer:
Angular speed = ω = 1.31×10⁴ rad/s
Explanation:
We know that the centripetal acceleration is given by
a = v²/r
The relationship between linear and angular speed is given by
v = ωr
Where ω is the angular speed
So the acceleration becomes
a = (ωr)²/r
a = ω²r²/r
a = ω²r
Re-arrange for ω
ω² = a/r
ω = √(a/r)
The acceleration is
a = 3.5×10⁵g
where g is the gravitational constant
a = 3.5×10⁵*9.81
a = 3.434×10⁶ m/s²
Finally, the required angular speed is
ω = √(3.434×10⁶/0.02)
ω = 1.31×10⁴ rad/s
