    Speed-Time Graph 2

    A particle is projected vertically upwards from the gorund with a speed of 80 m/s. Sketch the speed-time graph and find the total time of flight. (Take the acceleration due to gravity to be 10 m/s^2).

    linear graph, correct?

    v_0 = 80 , v_f = 0 , what is the value of t if a = -10 \, m/s^2 ?
