Explanation:
İf system ideal ( no frictional force )
Fnet=m.a
20=10.a
a=2m/s2
Answer: They travel equal distances
Explanation:
Distance is amount of space covered from one point to another. It is measured in metres. Distance = speed x time taken
In this case,
- Since Tony and Tanya both run at the same speed: let speed = b
- Also, both run for the same amount of time: let time = c
Therefore, distance covered by Tony and Tanya = speed x time taken
Distance = b x c
Distance = bc (i.e Tony travelled a distance of bc, so also Tanya)
