1. The problem statement, all variables and given/known data A box is on a 10 degree hill what is the force i have to pull to make the box move? and what force do i need to make the box move 20 meters mass of the box: 12.000 Coefficient of friction: 0.08 speed 1 m/s 2. Relevant equations Ffriction= μ * Fnormal F= m*a 3. The attempt at a solution Fnormal = Fgravtity* cos 80 Fn = (12,000* 10) * sin 80 Fn= 118177 Fn =118kN Ffriction= μ * Fnormal Ffriction= 0.08* 118 Ff= 9,45 kN The total force to make the box move = 9,45 +120 * cos 80 = 30 kN Is this correct? F = m * a I wanna be at 1 m/s in 4s F = 10.000 * 0,25 F= 2500N. Do I have to pull 30kN to make the box move and then pull 2,5 kN or do i have to pull 32,5kN? And when I achieve the 1 m/s what is the necessary force to make it a constante speed?
