Answer:
The kinetic energy at the bottom of the slide is equal to the potential energy at the top of the slide less the energy lost due to the frictional force.
Knowing the kinetic energy, the velocity can be calculated.
So, the data required is the height of the slide, angle of inclination of the slide and the coefficient of kinetic friction.
If the speed at the bottom of the slide is negligible the potential energy would be equal to the work done due to friction.
