The force of 5N and a force of 8 N act at the same point and inclined at 45deg. To each other. Find the magnitude and direction of the resultant force.

Explain how a parallelograme of law of force may be applied to velocities.

That is your work and you have to give it a try first. What did you do? Why did you do that?

Post those first, then we'll try to spot where you are stuck and help you out.

I did try it but I didn't get the correct answer. I don't know whatvi did wrong

35.3 real answer is 24.8 but I don't know hot to get that answer
