The largest grand piano in the world is really grand. Built in London, it has a mass of 1.25 × 103 kg. Suppose
a pianist finishes playing this piano and pushes herself from the piano so that she rolls backwards with a
speed of 1.4 m/s. Meanwhile, the piano rolls forward so that in 4.0 s it travels 24 cm at constant velocity.
Assuming the stool that the pianist is sitting on has a negligible mass, what is the pianist’s mass?
