Explanation:
A force that leads to movement of an object is known as work.
The energy present in an object due to its position in a gravitational field is known as gravitational potential energy.
Kinetic energy is the energy obtained by an object due to its motion.
For example, when Jerome is swinging on a rope then there occurs movement in the swing due to which the swing has kinetic energy.
Since, a force has been applied on the swing to make it move. Hence, a work is also done.
Therefore, we can conclude that if Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, work is being done.

<h3><u>Answer;</u></h3>
a) 5.00 x 10^8 J
<h3><u>Explanation;</u></h3>
The work done to move the sailboat is calculated through the equation;
W = F x d
where F is force and d is the distance.
Substituting the known values from the given above,
W = (5.00 x 10⁴ N)(10 km)(1000 m/ 1km)
= 5.00 x 10⁸ J
Thus, the work done is <u>5.00 x 10⁸Joules</u>
Answer:4.93 m/s
Explanation:
Given
height to reach is (h )1.24 m
here Let initial velocity is u
using equation of motion
here Final Velocity v=0
a=acceleration due to gravity
u=4.93 m/s
Answer:
Because the energy is waning
