Question

A motor bike running at 80 m/s is slowed down to 30 m/s in
2.5 seconds calculate the acceleration

Answer 1

Answer:

-20m/s²

Explanation:

Hloo mate, here is your answer

given ,

u = 80m/s  ,  v = 30m/s  ,  t = 2.5s  , a = ?

we know that , a = v - u/t

ie, a = 30 - 80 / 2.5

ie, a = -50/2.5

ie, a= -20m/s²
