Question

a particle is moving eastwards with a velocity of 5m/s.in 10s the velocity changes to 5m/s Northwards.find the average acceleration in this time.​

Answer 1

Answer:

as the velocity is changing in a plane we have to solve it vectorialy..

Answer 2

Answer:

1 ÷ (2)^1/2

Explanation:

a = (Vf - Vi ) ÷ t = (5j^ - 5i^) ÷ 10

= -5 (2)^1/2 = - root 2 ÷ 2 = -1÷ (2)^1/2.

Since, negative value is present it's in N-W direction
