An out fielder throws a cricket ball with
an initial kinetic energy of 800J and an
infielder catches the ball when its kinetic
energy is 600J. If the path of the ball
between them is assumed straight and is
20m long, the air resistance acting on
the ball is
1)26.6N 2)1.33N 3)100N 4110N.

Explanation:
Correct option is D)
Loss in kinetic energy is due to the air resistance, which is the work done by the air.
∴W
f
=ΔKE
⇒F×S=800−600=200
⇒F=200/20=10N
