2. You swing a yo-yo about your head in a horizontal circle, then you swing another one with twice the mass, and twice as fast with the same string. How do the tensions in the strings differ? In what direction must the force (tension) act on the yo-yo? What exerts the force?

Please include full solution and explanation! And please answer this question right away!!! Thank you so much!

HW1.4. 2D Moment resultant Two forces lying in the x-y plane are defined by their magnitudes and direction angles, as shown in the figure below. Force F₁ has a magnitude F₁ = 360 N, an angle 0₁ = 109°, and acts at point A (310, 0) mm. Force F₂ has a magnitude F₂ = 270 N, an angle 02 = 56°, and acts at point B = (0,385) mm. Determine the total moment about point O due to these two forces. Remember to follow the standard sign convention for clockwise (-) and counter-clockwise (+) moments. y B 10 02 F₂ F₁ A 0₁ X TEGINGEN

Help me with this hard complexed question, detailed, well explained and written on a sheet please it will be very helpful. Thank you!

Indicate all forces on the following system: make sure to label as well.
