Answer:
sorry I hate when people press your question and answer with a fake answer for points, however you said it was 100 points and it's not even close lol but it is "your speed Is constant" that is not true
The correct answer to the question is: 78.4 J
EXPLANATION:
As per the question, the mass of the apple is given as m = 4Kg.
The apple is present at a height of 2 m from the ground.
Hence, height of the apple h = 2 m.
We are asked to calculate the energy possessed by the apple.
The energy of the apple is nothing else than the gravitational potential energy of the apple.
The gravitational potential energy of a body at a height h is calculated as -
Gravitational potential energy P.E = mgh
Here, m is the mass of the body.
g is known as acceleration due to gravity and it's value is g = 9.8 m/c2
The potential energy of the apple is calculated as-
P.E = m × g× h
= 4 × 9.8 × 2 Joule
= 78.4 J ( Ans )
Hence, the energy of apple is 78.4 J.
Answer:
<h2>6 joules</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 3 × 2
We have the final answer as
<h3>6 J</h3>
Hope this helps you
