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 x component is 3 and the y component is 4, then you should enter 3,4.
1.Let the direction be the angle, that the vector makes with the +x-axis measured counterclockwise. Calculate the direction of the bird's velocity at t=2.0s.
2.Calculate the magnitude of the bird's acceleration at t=2.0s.
3.Calculate the direction of the bird's acceleration at t=2.0s
4.At t=2.0s, is the bird speeding up, is it slowing down, or is its speed instantaneously not changing?

An unsuspecting bird is coasting along in an easterly direction
at 1.00 mph when a strong wind from the south imparts a constant
acceleration of 0.300 m/s2. If the wind\'s acceleration lasts for
3.40 s, find the magnitude r and direction θ (measured
counterclockwise from the easterly direction) of the bird\'s
displacement over this time interval. (HINT: assume the bird is
originally travelling in the x direction and there are 1609 m in 1
mile.)
