suppose a treadmill has an average acceleration of 4.7 x 10^-3 m/s^2.
a. how much does its speed change after 5.0 min?
b. if the treadmill's initial speed is 1.7 m/s, what will its final speed be?

  1. a. (acceleration)*(time in seconds)
    = 4.7*10^3*300 = 1.41 m/s

    b. (initial speed) + (speed change) = ? m/s
    = 1.7 + (answer of part a)= ?
