Given the following data;

Workdone = 50 Joules

Time = 0.5 seconds

To find the power needed;

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

[tex] Power = \frac {workdone}{time} [/tex]

Substituting into the formula, we have;

Power = 50/0.5
