# Imagine that a sprinter accelerates from rest to a maximum speed of 10.3 m/s in 1.8 s. In what time interval will he finish the 100-m race if he keeps his speed constant at 10.3 m/s for the last part of the race? What assumptions did you make?

Question

Imagine that a sprinter accelerates from rest to a maximum speed of 10.3 m/s in 1.8 s.

In what time interval will he finish the 100-m race if he keeps his speed constant at 10.3 m/s for the last part of the race?
