Calculating the resultant force using vector

AI Thread Summary
To calculate the resultant force on the parachutist, first break down the forces acting on him into their components. The upward force is 500 N, while the downward force is 1000 N. The wind force of 300 N at a 45-degree angle needs to be resolved into its X and Y components using trigonometric functions: the X component is 300 cos(45) and the Y component is 300 sin(45). After determining these components, sum the forces in the Y direction (upward and downward) and combine them with the X component from the wind to find the overall resultant force. This approach utilizes vector addition and Pythagorean theorem for the final calculation.

Please HELP!

I need help with a question...I don't know how to do it...can someone please tell me how.
This question is about calculating the resultant force using vectors.

Question:
There is a parachutist with a 500 N force acting upwards on him and a 1000 N force acting downwards on him. There is also a 300 N force of wind acting towards him at a 45 degree angle. How do I calculate the resultant force on the parachutist?

thank you for your time

So you have:

Forces in Y:
500N, 1000N

The force that act at a certain degree should be expressed in Y and X components:
If the wind of 300 N comes from below at 45 degree angle:

X component of the 300 N force: 300 x cos (45) = xxx N
Y component of the 300 N force: 300 x sin (45) = xxx N


to calculate the resultants of all forces use pythagoras
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
