Answer:
41.07 m
Explanation:
According to the data:
Velocity = 2.65 m/s
Time = 15.5 s
Now the formula to calculate the distance is
Distance = Velocity x Time
Distance = 2.65 x 15.5
Distance = 41.07 meter
Kindly note that the person suddenly started to run at the velocity which is mentioned later that is 2.65 m/s.So the velocity given before is just ignored and we don't have to use any of the three equations of motion of kinematics.
Compared to energy-flow in ecosystems, the flow of matter <span>reflects conservation and recycling.
For example, let's take a look at the food chain system. Every time an organism is consumed by another organism, the energy that is given to the eater is only about 10% of the total existing energy
