The average speed of the person over the entire trip is 3.75 m/s.
<h3>Average speed of the person</h3>
Average speed = total distance/total time
Average speed = (d + d)/(d/Va + d/Vb)
where;
- d is the distance in a single trip
- Va is speed from point A
- Vb is the speed from point B
Average speed = (2Vavb)/(Va + Vb)
Average speed = (2 x 5 x 3)/(5 + 3)
Average speed = 3.75 m/s
Thus, the average speed of the person over the entire trip is 3.75 m/s.

Answer:
Angle of reflection of light is 34 degree
Explanation:
As per law of reflection of light we know that
angle of incidence of light = angle of reflection of light
So here we know that
angle of incidence on the surface of oil is given as
so we know that
so here we can say that reflection angle of light will be same as angle of incidence
Explanation:
work input is the work done by the machine in lifting the drum = Force × distance
100N × 10m
= 1000 J
