F - False.
Its greatest kinetic energy is at the point of release.
It has the least kinetic energy, zero, at its highest point in its path.
An object's location, velocity, acceleration, and direction can all be used to define motion.
Define velocity:
Velocity and speed describe how quickly or slowly an object is moving. We frequently encounter circumstances when we must determine which of two or more moving objects is going faster. If the two are travelling on the same route in the same direction, it is simple to determine which is quicker. It is challenging to identify who is moving the quickest when their motion is in the other direction. The idea of velocity is useful in these circumstances. Learn what velocity is, how it is measured, an example of velocity, and how it differs from speed in this article.
Motion may be described using an object's position, velocity, acceleration, and direction.

Answer:
0.51 m
Explanation:
Using the principle of conservation of energy, change in potential energy equals to the change in kinetic energy of the spring.
Kinetic energy, KE=½kx²
Where k is spring constant and x is the compression of spring
Potential energy, PE=mgh
Where g is acceleration due to gravity, h is height and m is mass
Equating KE=PE
mgh=½kx²
Making x the subject of formula
Substituting 9.81 m/s² for g, 1300 kg for m, 10m for h and 1000000 for k then
From the calculations, the speed of sound in this case is 16.9 m/s.
<h3>What is an echo?</h3>
The term echo has to do with the reflection of sound waves. Sound is a mechanical wave.
we know that the speed of sound is obtained from;
V = 2x/t
x = distance covered
t = time taken
V = 2(500)/59
v = 16.9 m/s
The error in the experiment could come from;
- Lack of precise time measurement
- Error can also arise from the environment of the experiment
