Initial speed = 40 km/h
Initial speed = 11.11 m/s
u = 11.11 m/s
Final speed = 80 km/h
Final speed = 22.22 m/s
v = 22.22 m/s
acceleration = change in velocity ÷ time
a = v - u ÷ t
a = (22.22 - 11.11 ÷ 10)m/s sq
a = (11.11 ÷ 10)m/s sq
a = 1.11 m/s sq
Initial speed = 11.11 m/s
u = 11.11 m/s
Final speed = 80 km/h
