Adam and Krystal are pulling their little brother in a sled up a snow-covered hill. If Adam is pulling north with a force of 120 N and the net force is 200 N north, with how much force and in which direction is Krystal pulling?


A.80 N north
B.80 N south
C.320 N north
D.320 N south

Respuesta :

If Adam is pulling with a pulling force of 120N, and the nets pulling force is 200N, and they are both going north, then that means that Krystal would have a a pulling force of 80N north, as 200N- 120N is 80N. She would be pulling north because she is on the same side as Adam, helping to pull the sled upwards.

-Hope this helps! xo
