A small squirrel jumps from pole 1 to pole 2 in horizontal direction. Squirrels is observaed by a very small observer at origin. What is average velocity vector of squirrel ? If average velocity vector is expressed as `v_(x)hat(i)+v_(y)hat(j)+v_(x)hat(k)`, express your answer as sum of magnitudes of its components `|v_(x)|+|v_(y)|+|v_(z)|` in unit m/s.

Answer

5

Explanation

`t=sqrt((2h)/(g))=sqrt((2xx5)/(10))=1s`
`v_(x)=(x)/(t)=(50)/(1)=50m//s`
`v_(y)=(y)/(t)=(50)/(1)=50m//s`
`v_(z)=(z)/(t)=5m//s`
