During a lawnmower race, a rider starts from rest and accelerates at 1 m/s/s for 10 seconds. The rider then maintains a constant velocity for the remainder of the race, which takes an additional 20 seconds.
A) How far was the race?
B) What was the lawnmower's average velocity for the race?

  • Physics -

    distance= 1/2 *1*10 + 1*10*20

    average velocity= distance/30seconds

    check my thinking.
