If it is eight meters per second, and the total distance he has to travel is four hundred meters to complete the race, you divide the total length needed to travel by the average speed per second to see the amount of seconds required to complete the race at that speed.
8 meters per second: Speed of runner
400 meters: Total distance
400/8=50
50 seconds to complete the race at the eight of 8m/s.
Answer:
Yes, Roberto will have twice the kinetic energy
Explanation:
The equation for kinetic energy is Ke = 1/2(<em>m</em>)v^2
The variable <em>m</em> is not squared by anything, which means it is directly proportional to the equation. If you were to multiply <em>m</em> by 2, it would in turn multiply the entire equation by 2, getting you an outcome with twice as much kinetic energy.
