A person pushes horizontally with a force of 270 N on a 55 kg crate to move it across a level floor. The coefficient of kinetic friction is 0.25.

What is the magnitude of the frictional force? What is the magnitude of the crate's acceleration?

1 answer

frictionforce=mu*mg=.25*55*9.8 N

net force= ma
270-frictionalforce= mass*a
solve for a
