Answer:
F=5.7×10⁻⁶
Explanation:
Not knowing a formula outright, I decided to follow the units of some relationships I did know. Radiation pressure is defined as force per area and also intensity divided by velocity (the speed of light here of course). Breaking intensity down into power per area and isolating force gave me the relationship F=(Power/Velocity),where power is given and the velocity is a constant.
My work is in the attachment, where I double checked the units too, comment with any questions.
Given :
A bicycle racer rides from a starting marker to a turnaround marker at 10 m/s.
She then rides back along the same route from the turnaround marker to the starting marker at 25 m/s.
To Find :
Her average speed for the whole race.
Solution :
We know, average velocity is given by :
Therefore, average speed for the whole race is given by 17.5 m/s.
