Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

2. After one month of taking a literature class, a first-year Bard
student decides to dispose of all the poctry he wrote in high
school. Placing his poetry in a large box that ends up with a
total mass of 40 kg, he pushes the box up a frictionless 25°
slope that leads to a large cliff dropping into a bottomless
chasm. Starting from rest and continually exerting a 500N
force in the horizontal direction on the box, how long does it take him to push the box 50 meters
the slope to the cliff?
