The terminal speed of the ball is,
D=Cρv2A2
mg=Cρv2(πd24}{2}
m=Cρv2(πd2)8g
Substitute the values
m=(0.207)(1.2 kgm3)(26 ms)2(π)(6.5 cm)2(102 m1 cm)8(9.8 ms2)
=0.028 kg
28 g

As part of your work out, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when u push the platform, you compress the springs. You do 80.0G of work when u compress the springs 0.200m from their uncompressed length.
a) What magnitude of force must u apply to hold the platform in this position?
b) How much additional work must you do to move the platform 0.200m farther, and what maximum force must you apply?
