Answer:
ok
Explanation:
Initial velocity, u = 600km/h
Final velocity, v = 1100km/h
Acceleration = 10km/h/s=600km/h2

Answer:
Initial velocity u = 600km/h
final velocity v = 1100km/h
acceleration = 10km/h/s = 600 km/h
a = (v-u)/t
t = (v-u)/a
t = ( 1100‐600)/600
t = 500/600 = 5/6hr = 50 sec.
hope it helps you
