a tractor with 2000 kg of mass pulls a plow equal to 80.0 kg, exerting a 200 N force on it. The tractor and plow set moves horizontally to the right with an acceleration of 0.500 m / s2. The resistance force that the soil exerts on the plow has a modulus, in Newton, equal to?

Respuesta :

Answer:

The resistance force that the soil exerts on the plough is 160 Newtons.

Explanation:

Fr = m.a

Fr = 80. 0,5

Fr = 40 N

Ft - F = Fr

200 - F = 40

F = 200 - 40

F = 160 Newtons
