A particle is moving with velocity 5 m/s towards cast and its velocity changes to 5 m/s north in 10 s, find the acceleration .

A

`sqrt(2)` N-W

B

`(1)/(sqrt(2))` N-W

C

`(1)/(sqrt(2))` N-E

D

`sqrt(2)N-E`

Text Solution

Verified by Experts

The correct Answer is:
B

`bar(a)=(bar(V_(t))-bar(V)_(i))/(Deltat)`
`bar(a)=(5hat(j)-that(i))/(10)`
`|bar(a)|=(5sqrt(2))/(10)=(1)/(sqrt(2))"m/s"^(2)`
