Answer:

The force exerted by the child is 38.25 Newton

Explanation:

We use the formula F=mxa (m=mass and a= aceleration):

F= 45kg x 0,85 m/s2=38, 25 kgxm/s2= <em>38, 25 N</em>

A 160-N child sits on a light swing and is pulled back and held with a horizontal force of 100 N. The magnitude of the tension f

guajiro [1.7K]

Answer:

T = 190 N

Explanation:

When child is sitting on the swing then the weight of the child is vertically downwards

So it is

$F_g = 160 N$

now a force of 100 N is acting on the swing in horizontal direction

so it is given as

$F_x = 100 N$

now the net force is resultant force due to gravity and horizontal force

so it is given as

$T = \sqrt{F_x^2 + F_g^2}$

$T = \sqrt{100^2 + 160^2}$

$T = 190 N$
