Answer: Time.
Explanation:
Hey there!!!
The reason is,
According to the question we have,
Initial velocity = 0m/s { as it starts from rest}.
Final velocity = 650 m/s
acceleration = 5m/s^2.
Looking on this formula,
Where "v" represents final velocity, "u" represents initial velocity and "a" represents acceleration. We dont have is time "t".
So, it's obvious that tine is an unknown variable.

In this scenario, only conservative force is acting on the ice-cream hence energy is conserved.
Now, you know that ice-cream was held at a height of 1.75 m from ground. Taking ground( h= 0 meters) as reference,
Total energy of ice-cream before it fell = Total energy after it reached the ground.
Once ice-cream falls, all its GPE is converted into kinetic energy. Kinetic energy will be maximum just before it hits the ground. And since ice-cream is inelastic substance, it will come to at rest. That is, its GPE will be zero on the ground

<u>Answer:</u>
energy only
<u>Explanation:</u>
Water waves transfer energy via oscillations of the water molecules, but the the water molecules themselves do not move along the wave.
This is why when the boy jumps into the water, his kinetic energy is transferred by the water molecules across the pool, but neither the boy nor the water particles move along with the wave.
