Jeff is pushing a rock up a hill with a force of 85 N. If Chris comes to help and Chris can push with a force of 60 N, what is the net force on the rock

Respuesta :

Answer:

F = 145 N

Explanation:

Given that,

Force applied by Jeff is 85 N and the force applied by Chris is 60 N. Both forces are acting in the same direction to push a rock up a hill. It means that net force is equal to the sum of these two forces.

So,

Net force on the rock = 85 N + 60 N

= 145 N

Hence, the net force on the rock is 145 N.
