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 $a = -10 \, m/s^2$ ?
