A softball pitcher throws a 0.17 kg ball toward a batter who is 20 m away. The

ball is traveling at 22 m/s when it leaves the pitcher's hand. What is the ball's
kinetic energy at this point?
OA. 4 J
OB. 82 J
C. 41 J

Answer:

C

Step-by-step explanation:

Kinetic Energy formula :

K.E. = 1/2mv²

=============================================================

Given :

⇒ mass = 0.17 kg (needed)

⇒ distance = 20 m (not needed)

⇒ velocity = 22 m/s (needed)

============================================================

Solving :

⇒ K.E. = 1/2 × 0.17 × (22)²

⇒ K.E. = 11 × 0.17 × 22

⇒ K.E. = 1.87 × 22

⇒ K.E. = 41.14 ≈ 41 J
