A runner covers the last straight stretch of a race in 5 s. During that time, he
speeds up from 5 m/s to 10 m/s. What is the runner's acceleration in this part
of the race?

Answer:

1 m/s²

Explanation:

acceleration = (final velocity (speed in this case) - initial velocity. ) ÷ time taken.

a = ( 10m/s - 5m/s ) ÷ 5s

a = 5m/s ÷ 5s

a = 1m/s².

hope it helps. :)
