Explanation:
gravitational potential energy at the top of the hill, which transforms into kinetic energy as he moves bottom of the hill
that's mean potential energy transfoms into kinetic energy
Since unbalanced forces acts on the spheres, the aim of increasing the release distance of the spheres is to observe the effect of unbalanced forces acting on the spheres.
<h3>What is an experiment?</h3>
An experiment is a study whose objective is to study cause and effect relationships. In this case, the students had to increase the distance at which the spheres was released.
The aim of increasing the release distance of the spheres is to observe the effect of unbalanced forces acting on the spheres.

I believe the answer is the core.
Answer:
<h3>The answer is 67.5 kg</h3>
Explanation:
To find the mass of an object given it's momentum and velocity we use the formula
where
p is the momentum
v is the velocity
From the question
p = 1080 kgm/s
v = 16 m/s
We have
We have the final answer as
<h3>67.5 kg</h3>
Hope this helps you
Answer:
Explanation:
If a rocket (firework) is launched
with an initial velocity of 39.2 meters per second at a height of 1.6 meters above
the ground, the equation h = -4.9t2
+ 39.2t + 1.6 represents the rocket’s height h in
meters after t seconds. The rocket will explode at approximately the highest point.
Fire official require the fireworks to explode at a height greater than 76 feet in
order for debris to land in Lake Michigan and not on the festival sight. The event
planners assured the fire officials that the fireworks would reach a height greater
than 76 feet
