Question

The coordinates of a bird flying in the xy-plane are given by x(t)=αt and 

y(t)=3.0m−βt2 , where  α=2.4m/s  and  β=1.2m/s2 . part a:Calculate the velocity vector of the bird as a function of time. Give your answer as a pair of components separated by a comma. For example, if you think the xcomponent is 3 and the y component is 4, then you should enter 3,4. part b:Calculate the acceleration vector of the bird as a function of time. Give your answer as a pair of components separated by a comma. For example, if you think the x component is 3 and the y component is 4, then you should enter 3,4

Answer 1

α
`=2.4 (m)/(s)`

β
`=1.2 (m)/(s^2)`


`x(t)=at`


`y(t)=3-`β
`t^2`


`Vx(t)=`α


`Vy(t)=-2`β
`t`


`vectorV=[`α
`;-2`β
`t]`


`ax(t)=0`


`ay(t)=-2`β
`t`


`vector a [0;-2`β
`t]`
