The total force applied by the three people is:
This force is pushing toward the direction of the motion, while the frictional force
points in the opposite direction.
We can write Newton's second law applied to the block: the resultant of the two forces must be equal to the product between the block's mass and its acceleration
We know the mass of the block, m=500 kg, and the acceleration,
, so we can find the friction:
