Answer:
W = 285.62 N
Explanation:
It is given that,
Mass of Jessica is 55 kg
Slope of the hill is 32 degrees
We need to find the component of her weight that is along her direction of motion.
The component along her direction of motion is shown in attached figure. It means
![W_y=mg\sin\theta\\\\W_y=55\times 9.8\times \sin(32)\\\\W_y=285.62\ N](https://tex.z-dn.net/?f=W_y%3Dmg%5Csin%5Ctheta%5C%5C%5C%5CW_y%3D55%5Ctimes%209.8%5Ctimes%20%5Csin%2832%29%5C%5C%5C%5CW_y%3D285.62%5C%20N)
So, the component of her weight that is along her direction of motion is 285.62 N.
