A 20 Kg Wooden crate rests on the wooden floor of a warehouse. What is the minimum horizontal force which must be exerted on the crate to get it to start sliding across the floor? Once it starts to move, how much force is needed to keep the crate moving at constant velocity?
m= 20 Kg
Ff=ma F=ma F=mg+ma
Ff=,58(20 x 9.8) 113.7=20a F=20(9.8)+20(5.7)
Ff=113.7 a=5.7 F=310N
The Attempt at a Solution
Above ^^. I do not know if my force is correct and how to find the constant velocity part!
