My answer for 1,2, and 4 is
right. Only 3 is wrong so please give me the solution and answer of
3.
If, after the ball being caught by the left person, the beam
moves a distance x to the right, Then position of each of the four
masses including the centre of mass of the beam will be displaced
to the right by x. We use this, considering the fact that the
centre of mass of the system remains at the same place, to find the
value of x which will also be the new position of person at the
left because he was at origin initially

A person with mass m1 = 61 kg stands at the left end of a uniform beam with mass m2 = 104 kg and a length L = 2.6 m. Another person with mass m3 = 68 kg stands on the far right end of the beam and holds a medicine ball with mass m4 = 8 kg (assume that the medicine ball is at the far right end of the beam as well). Let the origin of our coordinate...

Four objects are placed on a light (zero mass) six meter rod. The object on the left end has a mass of 3.65 kg, and the object on the right end has a mass of 3.8 kg. A third ball has a mass of 2.9 kg, a distance of 2.2 m from the left end. Finally, a fourth ball has a mass of 2.95 kg, a distance of 2.1 m from the right end. (a) How far is the center...
A gymnast with mass m-41 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m - 107 kg and length L 5 m. Each support is 1/3 of the way from each end. Initially the gymnast stands at the left end of the beam. 1j What is the force the left support exerts on the beam? 2) What is the force the right support exerts on the t...

A person with mass mp - 70 kg stands on a spinning platform disk with a radius of R = 2.1 m and mass mg 187 kg. The disk is initially spinning at a 2 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.7 m from the center). 1) What is the total moment of inertia of the system about the center of the disk when...
A gymnast with mass m1 = 48 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 124 kg and length L = 5 m. Each support is 1/3 of the way from each end. Initially the gymnast stands at the left end of the beam. *How much extra mass could the gymnast hold before the beam begins to tip? Now the gymnast (not holding any additional...

Bob, whose mass is 90 kg, is out in a 4 meter long canoe that has a mass of 110 kg. Bob is sitting at the left end of the boat, which is 10 meters away from the shore. For reference, the shore is at x = 0. Suddenly Amy appears on the shore, yelling at Bob that she wants a tug-of-war rematch on solid ground. Bob, terrified of this threat, gets up and...

1. What is the angular momentum of a 0.240-kg ball rotating on the end of a thin string in a circle of radius 1.35 m at an angular speed of 15.0 rad/s ? 2. A diver can reduce her moment of inertia by a factor of about 4.0 when changing from the straight position to the tuck position. If she makes 2.0 rotations in 1.5 s when in the tuck position, what is her angular speed (rev/s) when in the...
