Question

study the velocity time graph and calculate​

Answer 1

$at \: initial \: point \: ( a) \: u = 0 \\ at \: point \: (b)v = 25m {s}^{ - 1} \\ in \: time \: of \: = 3s \\ a = \frac{v - u}{t} \\ a = \frac{25}{3} \\ a = 8.33m {s}^{ - 2} \\ at \: c \: point \: its \: velocity u= 15m {s}^{ - 1} \\ t = 1s \\ v = 25m {s}^{ - 1} \\ a = \frac{v - u}{t} \\ a = - 10m {s}^{ - 2} \\ distance \: travelled \: in \: abe = area \: of \: vt \: graph \\ \frac{1}{2} ae \times eb \\ \frac{1}{2} \times 25 \times 3 \\d = 37.5m$
