Sagot :

Answer:

Net force = 250 N

Explanation:

Given that,

The mass of a teacher, m = 75 kg

As the parachute opens, the system experiences a 1000N drag.

We need to find the magnitude of net force acting on the teacher. 2 forces are acting on her i.e. drag force and weight.

Net force,

F = mg-D

= 75(10)-1000

= -250 N

Hence, the net force is 250 N and it is acting in the upward direction.
