A particle moves towards east with velocity 5m/s. After 10 seconds its direction changes towards north with same velocity. The average acceleration of the particle is

Intial velocity=v1=5m/seast wards

then after time t=10sec

v2=5m/s north wards

sv= √V1/2 +√V2/2

=√25 +25

5√2

acceleration=velocity/time

5√2/10

√2/2+√2√2

1/√2 towards north west
