Moment of a force is defined as the turning effect obtained by the product of force to the perpendicular distance from a particular point.
Taking the pivot at the top of the ladder where it meets the wall.
Clockwise moments = Anti-clockwise moments
Wa + Fh = W(2a)
NOTE : The perpendicular distance from the pivot to force F is h since the force is horizontal. The other force F being at the pivot has no component ;)

Ok guys i need help in these , anyone who has time to spare !
A block of mass m1=3kg rests on a frictionless horizontal surface.A second block of mass m2 = 2kg from a cord of negligble mass that runs over a frictionless pulley & then is connected to the first block . The blocks are released from rest

An idea of how it looks ^
QUESTION
(a) Find acc of the two block after they are releaased
(b)what is the velocity of the first block after 1.2s after the release of the blocks, assuming the first block does not run out of room on the table and the second block does not land on the floor?
(c)How far has block 1 moved during 1.2s interval?
(d) what is the displacement of the blocks from their initial positions .4 seconds after they are release?

A rope is attached from a truck to a car of 1400kg.The rope will break if the tension is greater than 2500N.Neglecting friction , what is the max possible acceleration of the truck if the rope does not break.Should the driver of the truck be concerned that the top might break

In a phys lab a glider is released from rest on a frictionless air track inclined at an angle.If the glider has gained a speed of 25 cm/s in travelling 50cm from starting point , what is the angle of inclination of track

Could you tell which paper these questions are from? it would make it easier.
