A ball is thrown upward with an initial velocity of 14 m/s. At what time does the ball reach the high point in its flight? (Use the approximate value of g = 10 m/s2 and remember that the velocity is equal to zero at the high point.)

  • physics -

    v=v₀-gt
    v=0
    t=v₀/g=14/10=1.4 s

  • physics -

    apply formula
    v=u-gt
    v=0
    u=14
    g=10
    then t=1.4s
