Question

if a boy is running and atains a velocity of 6m/s in 30 seconds afetr some time it slows down uniformly by 4 m/s in 5 seconds .what is the acceleration in both the cases?

Plz answer quickly​

Answer 1

Explanation:

Answer:- a = 0.2m/s². a = -0.4m/s². Given:- u = 0 m/s. v = 6m/s. T = 30 s ... Now, it's speed be slow down. then in this case. u = 6 m /s. v = 4 m/s.
