During the hammer throw at a track meet, an 8.0 kg hammer is accidentally thrown straight up. If 784.0 J of
work were done on the hammer to give it vertical velocity, how high will it rise?

The height risen by the hammer when the work were done is 10 m.

The given parameters;

  • Mass of the hammer, m = 8.0 kg
  • Work done on the hammer, W = 780 J

Apply work energy - theorem to determine the height risen by the hammer when the work is done on it;

[tex]E = mgh\\\\h = \frac{E}{mg} \\\\h = \frac{784}{8 \times 9.8} \\\\h = 10 \ m[/tex]

Thus, the height risen by the hammer when the work were done is 10 m.
