When you turn on a fan its electrical energy changes into kinetic energy
The vertical forces add up to zero.
The net force on the object is 60N to the right.
F = m • a
60N right = (10kg) • (a)
a = (60N right) / (10kg)
a = 6 m/s^2 to the right
Multi-engine Commercial would be nice.
According to Hooke's Law formula. The force is proportional to the displacement of the spring. I believe
