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:

v_{f} = v_{i} + at

v_{f} = v_{i} + (F/m)t

v_{f} = (? m/s) + (? N / ? kg)(? s)

v_{f} = (? m/s) + (? m/s^{2})(? s)

v_{f} = (? m/s) + (? m/s)

v_{f} = ? m/s

Note:

a = F/m

a = (? N) / (? kg)

a = ? m/s^{2}

v_{i} =
? m/s
F =
? N
m =
? kg
t =
? s
