Answer:
a)=2 b)10m
Explanation:
Acceleration: change in velocity/time
change in velocity = 30m-20m= 10m
10/5====2m/s
Displacement: change in distance
==> 30m-20m==== 10m

Answer:
2m² and 125m
Explanation:
a. v = u + at
30 = 20 +ax5
5a = 10
a = 2m/s²
b. s = ut + 1/2 at²
s = 20x5 + 2x½x5²
s = 100 + 25
s = 125m
