Answer 1

@experimentX

Answer 2

must be easy, find acceleration first.
subtract it form g,
multiply it my mass, you will find the total force applied by air resistance.

Answer 3

acceleration is 9.4m/s2

Answer 4

find he drop in accn

Answer 5

find the answer, thank you !

Answer 6

i mean i found the answer, thank you for helping me !

Answer 7
