A particle is moving east wards with a velocity of 5 `ms^(-1)` In 10 S , the velocity changes to 5 `ms^(-1)` north wards. 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.
