Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.

A boy and his skateboard have a combined mass of 60.0 kg. After an initial shove, the boy starts coasting at 5.5 m/s along a level driveway. Friction brings him to rest in 5.0 s. The combined force of gravity on the boy and skateboard is 5.9 x 10^2N. What is the average coefficient of rolling friction between the driveway and the skateboard wheels? (An explanation would help too, thank you :)! )
Consider an F-16 in a steady level trim at 250 m/s. At this flight condition, the pilots changes the elevator angle which provides an additional force on the tail of AF = 3 kN. The tail is located at a distance d = 5.9 m from the center of mass of the plane. Assume the mass of the F-16 to be 15,000 kg and the pitch moment of inertia about the center of mass to be 275,000 kg.m². Calculate the magnitude of angular acceleration in rad/s². c.g. d ΔF
The center of gravity of a 3.00 {\rm kg} irregular object You need to move the center of gravity 2.00 {\rm cm} to the left by gluing on a 2.00 \rm kg mass, which will then be considered as part of the object. Where should the center of gravity of this additional mass be located? Express your answer with the appropriate units.
A skateboard of mass m rests on the top of a hemispheric dome of radius R. After giving the skateboard a small kick, imparting an initial speed of vo, it begins rolling down the dome. Let the angle 0 indicate the location of the skateboard as it rolls down the surface of the dome. R 1. Eventually, the skateboard will lose contact with the dome. Given m, R, vo, and g, find the angle 0. at which the skateboard loses contact. Express your answer symbolically (i.e. without numbers). Check your work. Suppose you choose m = 1.5 kg, vo = g = 9.81 m/s. In this case, your answer should evaluate to 0. = 34.2°. 4.5 m/s, R = 4.3 m, and 2. Given m, R, and g, determine the range of speeds for which it is impossible to remain in contact with the wall at all.

A pulley has a negligible mass (that means, the radius is not relevant). It is supported with a pin at the center (and is free to rotate). A rope goes over the pulley.

What is the speed of block B, after B has traveled 0.716 m? Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B
The device shown in the figure below is one version of a Russell traction apparatus. It has two functions: to support the injured leg horizontally and at the same time provide a horizontal traction force on it. This can be done by adjusting the weight W and the angle θ. For this patient, his leg (including his foot) is 90.0 cm long (measured from the hip joint) and has a mass of 11.4 kg. Its center of mass is 41.0 cm from the hip joint. A support strap is attached to the patient's ankle 13.0 cm from the bottom of his foot. 1) What weight W is needed to support the leg horizontally? Express your answer in newtons. 2) If the therapist specifies that the traction force must be 16.0 N horizontally, what must be the angle θ?
