The horizontal force required to move the crate at a study speed across the floor is 88.2 Newton and a single slight push is enough to move the create when coefficient of kinetic friction is zero.
If the coefficient of the kinetic friction between the crate and the floor is 0.36 and the mass of the great is 25 kg and the horizontal force required to move the crate at a steady speed across the floor can be given by,
Fr = uMg
Where,
u is coefficient of kinetic friction
M is the mass of crate
g is acceleration due to gravity.
To move the crate across the floor with a steady Speed the force applied must be equal to the force of the friction.
Putting values,
Fr = 0.36 x 25 x 9.8
Fr = 88.2 N.
So, a horizontal force of 88.2 N is required to move the crate.
If the coefficient of the kinetic friction between the floor and the crate is zero then a slide single push will be enough to move the create with a constant speed across the floor.
