An object with a mass of ? kg is traveling along with a velocity of ? m/s when a ? N net force acts upon it. What will become the object's velocity if the force acts for ? s?
Solution:
vf = vi + at
vf = vi + (F/m)t
vf = (? m/s) + (? N / ? kg)(? s)
vf = (? m/s) + (? m/s2)(? s)
vf = (? m/s) + (? m/s)
vf = ? m/s
Note:
a = F/m
a = (? N) / (? kg)
a = ? m/s2
vi = ? m/s F = ? N m = ? kg t = ? s
