Hi,

Can someone help me please?

I am just not getting this... I thought firstly you would work out the vertical force. I would do this by using 300 COS 45 (as I know the Hypotenuse is 45)
Which gets me a vertical force of 212. Then where would I go?

I have shown the diagram below.. Am I on the right track?

Well, first you should have defined what you direction you want to be positive and what you want to be negative.

For example, you can say that upwards is positive and in this case, you would add the force that you just got with the other upward force, which is 500 N upwards.

Then, subtract the downward force, which is 1000 N.

The resultant force is what you got here. If it is positive, it means the parachutist will go up with that force, is not, he is going down with that force.

I hope it helps! :)

PS: I am ignoring any force along the horizontal. Let me know if we should consider that too.
