We know that velocity is equal to the total displacement of an object over time.
Deriving from that equation, we can say that:
Okay, so here it goes:
The bicycle took 25.02 seconds to displace at 58.3 meters.

The energy carried by the incident light is
where h is the Planck constant and f is the frequency of the light. The threshold frequency is the frequency that corresponds to the minimum energy needed to eject the electrons from the metal, so if we substitute the threshold frequency in the formula, we get the minimum energy the light must have to eject the electrons:
