2. The distance between the centres of carbon and oxygen atoms in the carbon monoxide gas molecule is 1.13 x 10-10 m. Calculate the centre of mass of the molecule relative to the carbon molecule.
3.A rigid body is rotating in the right-handed sense about the axis Oz with a constant angular
speed of 2 radians per second. Write down the
the instantaneous velocity, speed and acceleration of the particle of the body at the point(4;-
3; 7), where distances are measured in meters.
4.A rigid body is rotating with constant angular speed 3 radians per second about a fixed axis
through the points A. (4; 1; 1), B. (2;-1; 0), distances being measured in centimeters. The
rotation is in the left-handed sense relative to the direction ??⃗⃗⃗⃗⃗ . Find the instantaneous
velocity and acceleration of the particle P of the body at the point (4; 4; 4)
