A particles is moving eastwards with a velocity of `5 ms^(-1)`. In 10 s, the velocity changes to `5 ms^(-1)` northwards. The average acceleration in this time is

Text Solution

Verified by Experts

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

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