Answer 1

(a) acceleration = (change in velocity)/(time taken)
$acceration = \frac{change \: in \: velocity \: }{time \: taken}$

$a = \frac{final \: velocity \: - initial \: velocity}{time \: taken}$

$a = \frac{20 - 20}{15}$

a = 0


(b) velocity = 20 m/s (given in the graph )

(c) distance = velocity . time

time = 15 seconds
velocity = 20 m/s
$d = 20 \times 15 = 300$

d = 300 m
