Explanation:
KE = 1/2 mv²
= 1/2× 2.1×30²
= 2.1×450
= 945j

Answer:
Answer
The Ball has
Kinetic Energy of > 945.
Given:
Mass of volleyball = 2.1 kg
Speed at which ball leaves
the hand 30 m/s
To Find:
.The energy of the ball
Solution:-
Given that,
The ball leaves the hand with
speed of 30m/s.
Hence, it is clear that the ball is
in state of motion and will
possess Kinetic Energy.
We know,
K.E =mv|
2
where,
.K.E = Kinetic energy
possessed by ball
m mass of the ball
V speed of the ball
Substituting in the Formula:-
K.E =x2.1 x (30)2
K.E = x 2.1 x 900
K.E = 1x 2.1 x 450
K.E =945 J
Therefore, the ball will have
Kinetic Energy and of 945 J.
