A net force of ? N acts upon an object with a mass of ? kg. If the object were initially moving with a velocity of ? m/s when the force was applied, what will be its displacement after ? s?
d = vit + (1/2)at2
d = vit + (1/2)(F/m)t2
d = (? m/s)(? s) + (1/2)(? N / ? kg)(? s)2
d = (? m/s)(? s) + (1/2)(? m/s2)(? s2)
d = (? m) + (? m)
d = ? m
Note:
a = F/m
a = ? N / ? kg
a = ? m/s2
vi = 1.0 m/s F = 1.0 N m = 1.0 kg t = 1.0 s
