The equation is Force = mass times acceleration so:
50 x 9.8 = 490 N

Answer: 490 Newton.

The length of ladder is, <em>l</em> = 3.4 m.

The mass of leah is, $m = 50$ kg.

The acceleration due to gravity is, <em>g</em> = 9.8 m/s².

When Leah stand on the ladder the force exerted by her on the ladder is equal to her weight. $F = W$

Weight of leah is,

$W=mg=50 \text k \text g \times 9.8 \text m / \text s^2 = 490 \text N$
