It is desired to predict the time t h that is needed for an object of mass

Question:

It is desired to predict the time t_h that is needed for an object of mass m to travel downward a distance h, if gravity is the only force.

(a) If the object is stationary before release, what could you conclude about t_h from dimensional analysis alone?

(b) How is the dimensional analysis changed if the object is propelled downward at an initial velocity U?

(c) Derive from basic mechanics the expression for t_h for U ≥ 0. When put in dimensionless form, how does it compare with what you found in parts (a) and (b)?
