A soccer ball is kicked from the top of a cliff in such a manner that its

`x`

and

`y`

components are given by

`x=(29.0(m)/(s))t`

and

`y=36.5m+(29.4(m)/(s))t-(4.90(m)/(s^(2)))t^(2)`

, where

`x`

and

`y`

will be in meters when

`t`

is in seconds. Determine the following. (Express your answer in vector form.) (a) displacement of the ball during the time interval

`\Delta t=0->3.00s`

`\Delta vec(r)=◻m`

(b) average velocity of the ball during the time interval

`\Delta t=0->3.00s`

`vec(v)_(avg )=(m)/(s)`

(c) acceleration of the ball during the time interval

`\Delta t=0->3.00s`

`vec(a)=`

`(m)/(s^(2))`
