A 120 kilogram crate is pulled across the floor with a constant force of 500 Newton that is applied at an angle of 25o above the horizontal. For the first 20 minute of travel the floor is frictionless and for the next 20 minute of travel the coefficient of kinetic friction is 0.25.

a. Find the speed of the crate after 20 meter of travel?

b. Find the speed of the crate after 40 meter of travel?
