Answer:
45 N
Explanation:
From the question given above, the following data were obtained:
Force applied by Brett = 25 N
Force applied by Chris = 20 N
Net force =?
From the question given above, Brett and Chris applied force to the piano in the same direction. Thus the net force acting on the piano will be the sum of the forces applied by Brett and Chris. This can be obtained as follow:
Force applied by Brett = 25 N
Force applied by Chris = 20 N
Net force =?
Net force = 25 + 20
Net force = 45 N
