Answer:

11.25m

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time of running  = 3s

Acceleration  = 2.5m/s²

Unknown:

Displacement = ?

Solution:

To solve this problem, we apply one of the motion equations.

  S  = ut + \frac{1}{2} at²

   u is the initial velocity

    t is the time taken

    a is the acceleration

 S = (0 x 3)  + ( \frac{1}{2}  x 2.5 x 3²)   = 11.25m

All that business about the crane and the rope and the falling
is only there to confuse us.

The piano ended up 5 meters above the ground.

           Potential energy = (mass) (gravity) (height)

                                   = (200 kg) (9.81 m/s²) (5 m)

                                   = (200 · 9.81 · 5)  (kg-m²/s²)

                                   =   9,810 joules   .
