If 2.0 J of work is done in raising a 180g apple, how far is it lifted?
If the object has travelled some distance (upwards) then there must be some potential difference (increased potential energy).
Thus the energy needed to lift the ball can be found by this formula:
Now we know the energy(2 J), the mass (0.18 kg), and gravitational energy (9.8 m/s^2). Putting into the formula we get:
height reached above the ground = 1.14 m
