A particle is moving eastwards with velocity of `5 m//s`. In `10 sec` the velocity changes to `5 m//s` northwards. The average acceleration in this time is.

Text Solution

Verified by Experts

`veca_(av)=(vecDeltav)/(Deltat)=(vecv_(f)-vecv_(i))/(Deltat)`

`veca_(av)=(5hatj-5hati)/(10)=(5 sqrt(2))/(10)=(1)/(sqrt(2))m//s^(2)`. North- west direction.
