A steel sphere is held by an electromagnet and released from rest.

Point B is 3.2 m vertically below the starting point A.

At point B, the momentum of the sphere is 0.48 kg m/s.

Calculate the mass of the steel sphere.

Acceleration due to gravity, g=10 m/s2g = 10 \text{ m/s}^2g=10 m/s2

A steel sphere suspended by an electromagnet at point A, 3.2 m vertically above a detector platform at point B. An arrow shows the downward direction of fall from A to B.
