In a 100 m race, Maggie and Judy cross the finish line in a dead heat, both taking 10.6 s. Accelerating uniformly, Maggie took 2.20 s and Judy 2.90 s to attain maximum speed, which they maintained for the rest of the race. What was Maggie's acceleration?

  • Physics -


    1/2 a*2.2^2 + 2.2a*8.4 = 100
    a = 4.78


    1/2 a*2.9^2 + 2.9a*7.7 = 100
    a = 3.77

    Thanks so much!!! If you have time can you help me figure out their max speeds?

  • Physics -

    Fot max speed, multiply the acceleration rate by the length of time that person accelerated
