Beginning at time t = 0, a student exerts a horizontal force on a box of mass 30 kg, causing it to move at 1.2 m/s toward an elevator door located 16 m away, as shown above. The coefficient of kinetic friction μk between the box and the floor is 0.20

Question

radar · Answer

What is being asked, where is the "shown above"

anonymous · Answer

what is the magnitude of the horizontal force that exerted on the box to move in 1.2m/s

radar · Answer

Is the 1.2 m/s the final velocity?

radar · Answer

Probably one of the three kinematic equations will be used, but I have not done this since 1980 and I've forgotten how!

anonymous · Answer

yes 1.2m/s is final velocity
