Answer:
1.23 m/s
Explanation:
p=mv
57.2 = 46.5v
v= 57.2/46.5
v= 1.23
If you want to verify your answer, just insert the value of v in the equation.
In this collision, 1/2 of the initial kinetic energy of the first glider is converted into thermal energy.
<h3>In plain English, what is kinetic energy?</h3>
An object's strength as a result ofstrength an object has as a result or motion is known as kinetic energy. Toorder to accelerate an object, a force must be applied. Applying force requires effort on our part. When the work is done, power is transported to the thing, which causes it to move at the athe new, constant pace.
<h3>What does kinetic energy mean, or what are some instances?</h3>
The motion energy is known as kinetic energy, and it is manifested when a particle, object, or group if particles moves. Any moving object uses kinetic energy, including people walking, baseballs being thrown, food falling from tables, and charged particles in electric fields.

Answer:
VR = 
Explanation:
Velocity ratio (VR) of a machine is a term that compares the distance moved by effort put into the machine to the distance moved by the load.
A wheel and axle is a device for lifting of a load through a height. It is made up of two circular parts called wheel and axle. Its velocity ratio (VR) can be determined by:
VR =
For a practical wheel and axle, the diameter of the wheel is greater than the diameter of the axle.
Answer:
Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science
