Answer 2

Answer:

Distance travel in 30 sec = 1800 m

Distance travel in 50 sec = 5000 m

Explanation:

Given :-

Initial velocity = 0 m/s

Final velocity = 120 m/s

Final velocity " = 200 m/s

Time = 30 sec

Time " = 50 sec

We know that ,

v = u + at

120 = 0 + 30a

a = 4 m/s

v" = u + a"t"

200 = 0 + 50a"

a" = 4 m/s

Now,

v² - u² = 2as

120² = 8s

s = 120*120/8

s = 1800 m

v² - u² = 2as

200² = 8s

s = 200*200/8

= 5000 m
