Question

A particles is moving towards north with velocity 5
m/s. In 5 second the velocity changes to 5 m/s
eastwards. The average acceleration in the time is​

Answer 1

Answer:

Pls mark me as brainliest

Step-by-step explanation:

a = (v - u)/ t

u = 5 j cap

v = 5 I cap

t = 5s

|v - u| = sqrt(5² + 5²) [Here |v - u| is the magnitude of vector v - u]

|v - u| = sqrt(2*5²)

|v - u| = 5*sqrt(2)

a = 5*sqrt(2)/5 = sqrt(2) m/s²
