Answer:

4.5 metres

Explanation:

Using Hooke's Law (F\propto x)

We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.

600=3k\\k=200

Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.

900=200x\\x=4.5

In the photo, a locomotive has broken through the wall of a train station. During the collision, what can be said about the forc
Pavlova-9 [17]

Answer:

Whether the force exerted by the locomotive on the wall was larger

Than the force the locomotive could exert on the wall.

Explanation:

The Newton's third law of motion States that every force have it's equal and opposite reaction force, whose magnitude is the same as the applied force. Therefore the magnitude of these opposite forces will be equal.

So we have;

F12=-F21

F12 is the force in a direction

-F21 is the force in the opposite direction.

Therefore we see that the magnitude of the force the locomotive exerts on the wall is equal to the one the wall exerts on the locomotive. Both magnitudes are equal but in opposite directions.

Mystical ride her scooter down the hill from the state of rest when she reaches the bottom of the hill 4.0 seconds later her spe
mina [271]

The acceleration is 2.5 m/s^2

Explanation:

This is a uniformly accelerated motion (constant acceleration), therefore we can apply the following suvat equation:

v=u+at

where

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

For the scooter in this problem, we have

u = 0 (it starts from rest)

v = 10.0 m/s is the final velocity

t = 4.0 s is the time interval

Solving for a, we find the acceleration:

a=\frac{v-u}{t}=\frac{10-0}{4}=2.5 m/s^2
