Well, there's three classes of levers or ramps, whatever you'd prefer to call them and if an object is rolling down a ramp that is going straight down, that is where it will end up unlike a ramp that is tilted slightly to the left or right.
I honestly think it's 18,000 N
Hope I helped!
<span>So if you started on the bench press with 8 reps of 225 pounds, but can now do 10 reps, and you've been able to achieve 10 reps for two workouts in a row, increase the weight.

Theres a little exclamation......
Answer:
Acceleration is rate of change of velocity.
The equation of turtle's position as a function of time is given by:
Differentiate the above equation to find the velocity as a function of time:
Differentiating further, we would get the equation for acceleration:
Therefore, initial acceleration is
Answer:
Hey buddy, here is your answer. Hope it helps you.
Explanation:
Solids.Sound travels fastest through solids. This is because molecules in a solid are packed against each other. When a vibration begins, the molecules of a solid immediately collide and the compression wave travels rapidly.Sound moves slowest through a gas. That’s because the molecules in a gas are spaced very far apart. In order for sound to travel through air, the floating molecules of matter must vibrate and collide to form compression waves. Because the molecules of matter in a gas are spaced far apart, sound moves slowest through a gas.
Sound travels faster in liquids than in gases because molecules are packed more closely together. This means that when the water molecules begin to vibrate, they quickly begin to collide with each other forming a rapidly moving compression wave.
<h2>Answer: A lever
</h2>
The catapult is basically a type of simple lever or first class lever, which is a device used to transmit force and displacement to an object, by means of the amplification of the applied mechanical force, thus increasing its speed or distance traveled.
These simple levers are composed of a rigid bar that can rotate freely around a <u>point of support</u> (the fulcrum). However what differentiates them from the other levers is that the <u>fulcrum</u> is between the point where the <u>effort</u> must be applied and the point where the <u>resistance</u> is.
With this configuration it is posssible to make several arrangements, depending on the purpose to be achieved, either control and decrease the speed and distance traveled by the object or increase it.
