If the string were to break at point II, what would be the path of the ball?

A $$50 kg$$ acrobat is swinging on a rope with a length of $$15 m$$ from one horizontal platform to another. Both platforms are at equal height.
If the maximum tension the rope can support is $$1200 N$$, which of the following answer best represents the maximum velocity the acrobat can reach without breaking the rope?

A plane banks its wings $${30}^{o}$$ relative to the horizontal to enter into a circular turn. The circular path has a radius of $$1500 m$$.
Which of these values best represents the velocity of the plane if the lift force exerted on the wings is equal to twice the weight of the plane?

Which of the following statements is true?

A ball of mass $$m$$ is attached with the string of length $$R$$, rotating in circular motion, with instantaneous velocity $$v$$ and centripetal acceleration $$a$$.

A uniform rod of mass 1 kg is hanging from a thread attached at the midpoint of the rod. A block of mass $$m$$=3kg hangs at the left end of the rod and block of mass $$M$$ hangs at the right side at 80 cm from block $$m$$. If system is in equilibrium. Calculate $$M$$.

The given rod is uniform and has a mass m. Find the tension in the string.

A $$110 kg$$ panda is riding on a $$3.0 m$$ long swing whose mass can be considered negligible. The highest point of its arc occurs when the swing makes a $${20}^{o}$$ angle with the vertical.
What is the magnitude of the total tension in the ropes of the swing at that point?

A uniform bar is lying on a flat horizontal table. The bar is acted upon by $${F}_{1}$$ and $${F}_{2}$$,besides the gravitational and normal forces (which cancel),   $${F}_{1}$$ and $${F}_{2}$$ are parallel to the surface of the table. If the net force on the rod is zero, then which one of the following statement is true?

Two objects rest on a seesaw. The first object has a mass of 3 kg and rests 10 m from the pivot. The other rests 1 m from the pivot. What is the mass of the second object if the seesaw is in equilibrium?
