Question

leah has a mass of 50kg and is using a 3.4m ladder. The acceleration is equal to 9.8 meters per second squared. What force, in Newtons,does Leah exert on the ladder when she is standing on it ?

Answer 1

We don't really care what size the ladder is. All we need to figure out is the quantity that most people call her "weight".

Weight = (mass) x (gravitational acceleration)

= (50 kg) x (9.8 m/s²)

= 490 Newtons .

(about 110.2 pounds)
