Anet force of fnet acts on an object, causing the object to accelerate at a rat of 9m/s/s. what is the acceleration rate in a second trial, if a new net force of 2fnet acts on the same object?

a) 3m/s/s
b) 4.5m/s/s
c) 18m/s/s
d) 81m/s/s

the answer is b, have negligible mass

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.

you can cut your hand off if your not
