I need help check my answerPlease!
number 23 only
The key is 133.25lb,
............99= [√(3960^2* 125)/Ws]-3960
( 99+ 3960)^2 = ([√(3960^2* 125)/Ws])^2
16.475.481*Ws = 1.960.200.000
............Ws=1.960.200.000/16.475.481
............Ws=118.98
my answer not match the key
Thank you

Hi,

 r+=+sqrt%283960%5E2W%5BE%5D%2FW%5Bs%5D%29+-+3960+

 99+=+sqrt%283960%5E2%2A125%2FW%5Bs%5D%29+-+3960+

 99+=+sqrt%283960%5E2%2A125%2FW%5Bs%5D%29+-+3960+

 4059+=+sqrt%283960%2A125%2FW%5Bs%5D%29

 W%5Bs%5D+=+%283960%5E2%2A125%2F4059%5E2%29

 W%5Bs%5D+=+1960200000%2F16475481 = 118.98lb

Weight in space is always less than weight on Earth.

133.25lb could not be a correct answer.
