The distance between the oxygen molecule and each of the hydrogen atoms in a water molecule is
and the angle between the two oxygen-hydrogen bonds is
. Treating the atoms as particles, find the centre of mass of the system
In a water molecule, let us consider the oxygen atom (O) and two hydrogen atoms (H_1) and (H_2). Let the distance between oxygen and each hydrogen atom be (r), and the angle between the two O–H bonds be (\theta). ________ __________ __________ __________ _______ _____ __________ __________ _________ ___ ____ ______.

A block of mass slides from rest at a height of
down to a horizontal surface where it passes over a
rough patch. After crossing this patch it climbs up another incline which is at an angle of
to the ground. The rough patch has a coefficient of kinetic friction
. What height does the block reach on the incline before it comes to rest?
The speed of an aeroplane is . The engines take in 80 kg of air per second and mix it with 40 kg of fuel. This mixture is expelled after it ignites and it moves at a velocity of
relative to the aeroplane. Calculate the thrust of the engine.
A ball has an angular velocity of counterclockwise. Some time later, after rotating through a total angle of 4.5 radians, the ball has an angular velocity of
clockwise. Determine the angular acceleration, the average angular velocity and how much time it takes for the ball to attain this velocity.
