A ship moves at a speed that is 85% the speed of light. Relative to a stationary observer, how much time will the ship experience when the stationary observer has experienced 2 hr?

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

it's a b and
