What would huifen's weight be if her mass is 54kg?

The weight of huifen is equal to 529.2 N.

Explanation:

Given that,

Mass of huifen = 54 kg

We need to find the weight of huifen. We know that, the weight of an object is given by :

W = mg

Where

g is acceleration due to gravity

Put all the values,

W = 54 × 9.8

W = 529.2 N

So, the weight of huifen is equal to 529.2 N.

If you want the true weight of someone, you need to multiply mass by gravity which is 54*9.81 giving the calculation in Newtons and this would equal 529.74N

Explanation:

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
