Answer:
The correct option is:
B) Kinetic Energy
Explanation:
We know that if a body is placed at a certain height, it possesses Potential Energy, which is represented by 'mgh'. In this case, when the skydiver is present in the plane, before jumping, he has potential energy as he is at height 'h'.
As Kinetic energy is given as '(1/2)mv²' dependent on velocity of the object, when the skydiver jumps of the plane, his height starts decreasing, which decreases his Potential Energy. As energy can neither be created or destroyed, but is converted to one form or another, all this Potential energy starts to convert into Kinetic energy. As Potential Energy decreases with distance, Kinetic energy increases. Hence, line B represents Kinetic Energy.
Answer:
a = 2.5 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 25 [m/s]
Vo = initial velocity = 0 (star from the rest)
a = acceleration [m/s²]
t = time = 10 [s]
25 = 0 + (a*10)
a = 25/10
a = 2.5 [m/s²]
