Question

During takeoff, a plane has a lift force of 690,000 N and a weight of 600,000 N.What is the net force acting on the plane?

Answer 1

Answer:

The net force = 90, 000N upwards

Explanation:

Note that:

the lift force is acting upwards

the weight of the plane acts downwards

The lift force = 690000N

The weight = 600000N

The net force = 690000 + (-600000)

The net force = 690000 - 600000

The net force = 90000N upwards
