" Una slitta da 30 kg accelera da ferma, ad una velocità di 3m/s in in 3.0 s . Calcolare la forza applicata alla slitta"
I calculate the applied force with the second law of dinamics:
F=m*a
a=Δv/Δt = 3/3 = 1 m/s^2
F=30*1=30N

@lucianop grazie
A m = 30 kg sled accelerates from rest to a speed V of 3,0 m/s in t = 3,0 s
> calculate the force F applied to the sled
force F = mass times acceleration
F = 30*ΔV/Δt = 30*(3-0)/(3-0) = 30 N

acceleration : a = (3 - 0)/3 m/s^2 = 1 m/s^2
force : F = m a = 30 Kg * 1 m/s^2 = 30 N

@eidosm thanks
a = (v - vo) / t = 3,0 / 3,0 = 1,0 m/s^2; (acceleration).
Force: (second law of dynamics):
F = m * a = 30 * 1,0 = 30 N ; (force applied to the sled).
