Determine la magnitud de la fuerza que se debe aplicar a un carrito de baleros que tiene una masa de 40kg para que cambie la magnitud de su velocidad de 0 a 3 m/s en un segundo
By definition we have the force is: [tex]F = m * a
[/tex] Where, m: mass a: acceleration. To find the acceleration we have the following formula: [tex]vf = a * t + vo
[/tex] Where, vo: initial speed vf: final speed a: acceleration t: time Clearing the acceleration we have: [tex]a = (vf - vo) / (t)
[/tex] Substituting values: [tex]a = (3 - 0) / (1)
a = 3 m / s ^ 2[/tex] Then, the force is given by: [tex]F = (40) * (3)
F = 120 N[/tex] Answer: The magnitude of the force that must be applied is: [tex]F = 120 N[/tex]
