Answer:
Deceleration of the runner is -23.33
Given:
Initial velocity = 3.5
Final velocity = 0
Time = 0.15 s
To find:
Deceleration of runner = ?
Formula used:
According to first equation of motion,
v = u + at
Where, v = final velocity
u = initial velocity
a = deceleration
t = time
Solution:
According to first equation of motion,
v = u + at
Where, v = final velocity
u = initial velocity
a = deceleration
t = time
0 = 3.5 + a (0.15)
-3.5 = 0.15 (a)
a =
a = -23.33
Negative sign shows that it is deceleration.
Thus, deceleration of the runner is -23.33
-- You've GOT the kinetic energy of the bullet.
-- That's the amount of work that has to be done to stop it.
-- work = (avg force) x (penetration) and they just gave you the average force.
-- Did you think it would be this easy ?
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>
⭐Hey
⭐Here we can use the formula for the body that is in free fall state. .
⭐that is
↪V = underoot 2*g*h
↪So the velocity will be ...
↪V = underoot 2 * 10 * 100
↪V = underoot 2000
↪V = 20 *underoot 5
↪V = 20 ( 2.23)
↪V = 44.6 m/s
