Starting from rest, a boat increases its speed to 4.92 m/s with constant acceleration.

(a) What is the boat's average speed?

(b) If it takes the boat 5.07 s to reach this speed, how far has it traveled?

  • physics -

    initial velocity = 0 m/s
    final velocity = 4.92 m/s
    constant acceleration so,
    (a) average velocity =
    (initial velocity + final velocity)/2

    (b) distance = average velocity x time

    substitute and calculate
