A pendulum is used in a large clock. The pendulum has a mass of 2kg. If the pendulum is moving at a speed of 4.1m/s when it reaches the lowest point on its path, what is the maximum length of the pendulum?

Answers

Answer 1

Answer: There's no way to calculate the length of the pendulum
with the given information.

The only thing we can calculate is the total energy in the pendulum.

When the pendulum is at the bottom of its swing, ALL of its energy
is kinetic.

   Kinetic energy = (1/2) x (mass) x (speed)²

   = (1/2) x (2 kg) x (4.1 m/s)²

   = 4.1 kg-m²/sec²

   = 4.1 Joules .

In principle, we can also calculate how HIGH the 'bob' is at the end of
its swing, because now we know how much total energy the pendulum
has, and at the ends of the swing, the energy is all potential.

   Potential energy = (mass) x (gravity) x (height)

   4.1 J = (2 kg) x (9.8 m/s²) x (height)

   Height = (4.1 kg-m²/s²) / (19.6 kg-m/s²)

   =    0.209 meter high

and that's as far as we can go. None of this points us toward
calculating the length of the pendulum.

Scott cuts a one meter long wire into five equal parts. What is the length of each part of the wire? (2 points) 0.02 centimeters 0.20 centimeters 20 centimeters 200 centimeters

Answers

20 centimeters. 100 centimeters in a meter. 100/5= 20

Answer: The length of each part of the wire 20 centimeter.

Explanation:

Length of the wire = 1 m

On dissecting the 1 meter wire into equal five parts = $(1 m)/(5)$

The length of the each part will be = $(1 m)/(5)=0.2 m$

1 meter = 100 centimeter

So, 0.2 meter = $0.2* 100 centimeter=20 centimeter$

The length of each part of the wire 20 centimeter.

Once a well has reached the water table, it will not run dry true or false? -earth science

Answers

No, this is false.

In principle, every well can run dry, and this includes a well that has reached the water table. If the water is taken from the well faster than it's replenishing itself, the well will run dry- and in this situation, typically people need to look for a new place to have a well.

Explanation:

When more than one force is acting on an object, the ____ determines the motion of the object.

Answers

When more than one force is acting on an object, the net force determines the motion of the object.

The net force of an object is expressed as a value, such as net force = 5, and the motion of the object will change depending on how high or low that value is. For instance, if the net force is 0, the object won't move unless it is already moving, but if it is larger than 0, its motion will change.

I have three questions. John has to hit a bottle with a ball to win a prize. He throws a 0.4 kg ball with a velocity of 18 m/s. It hits a 0.2 kg bottle, and the bottle flies forward at 25 m/s. How fast is the ball traveling after hitting the bottle? 2. Someone fires a 0.04 kg bullet at a block of wood that has a mass of 0.5 kg. (The block of woof is sitting on a frictionless surface, so it moves freely when the bullet hits it). The wood block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the woof block move together as one object. How fast are they traveling? 3. A big league hitter attacks a fastball. The ball has a mass of 0.16 kg. It is pitched at 38 m/s. After the player hits the ball, it is now traveling 44 m/s in the opposite direction. The impact lasted 0.002 seconds. How big of a force did the ballplayer put on that ball?
