The coordinates of a bird flying in the xy-plane are given by x(t)=αt and y(t)=3.0mβt2 , where α=2.4m/s and β=1.2m/s2
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 x component is 3t and the y component is 4t, then you should enter 3t,4t. Express your answer using two significant figures for all coefficients.
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 3t and the y component is 4t, then you should enter 3t,4t. Express your answer using two significant figures for all coefficients.
C.) Calculate the magnitude of the bird's velocity at t=2.0s
D.)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 .
E.) Calculate the magnitude of the bird's acceleration at t=2.0s
F.) Calculate the direction of the bird's acceleration at t=2.0s.

Driver controls on the left side
: Until a few years ago, U.S. cars exported to Japan had the driver controls on the left side (as in the United States). The Japanese (like the British), however, drive on the left side of the road, so Japanese cars sold in Japan have the driver contro..
