Conservation of Energy: Ball with and without Air Resistance

CLMECH-GLFG9J

When tossed vertically up in the air with an initial speed $v$, a ball of mass, $m = 100\space g$ reaches a maximum height of $3.2\space m$ in the absence of air resistance. With air resistance, the same ball tossed with the same initial speed only reaches a height of $2.8\space m$.

What force of air resistance acts on the ball?

A

$0.14\space N$

B

$0.39\space N$

C

$0.40\space N$

D

$0.98\space N$
