Answer:
V = U + at
Where V is final velocity = 40m/s,
U is the initial velocity = 0 and a is acceleration.
40 = a(20)
a = 2
S = Ut + (1/2) at^2
Where She is the distance travelled.
S = 0 + (1/2) *2*400
S = 400m
Average velocity =
Total distance travelled/total time taken
= S/t
= 400m/20sec
= 20m/s
Therefore, the average velocity is 20m/s
