Answer:
972 J
Explanation:
At the bottom, all the gravitational potential energy was converted into kinetic energy. If you calculate the GPE, its value will be the same that the KE at the bottom. The GPE can be calculated this way:
GPE = mass×gravity×heigth
GPE = 2.2×9.8×45.08 ≈ 972
Because the ball is a sphere and there's nothing that can actually stop a sphere unless you cover it with something that will actually stop it, for example like your hand.
<span> <span> The answer to your question is: increase the force applied to the object.
Two items are provided as a basis for that conclusion:
1. According to Newton's Second Law of Motion, the formula for finding force is: F = ma
where F is the force,
m is the mass of an object,
and a is the acceleration of the object.
And 2: work = force x distance or W = F x d.</span></span>
Answer:
Horizontal distance from the foot of the cliff is 40 m
Explanation:
Given :
Speed of stone 
Vertical distance 
m
Gravitational acceleration 
From the kinematics equation,
Where 
initial velocity ( 
)
So time take to fall down,
sec
Now find horizontal distance travel by stone,
m
Therefore, the horizontal distance travel by stone is 40 m
I’m so sorry, I need more information. Good luck and I’m sorry I couldn’t help you :(
