The position of a squirrel running in a park is given by r=[(0.280m/s)t+(0.0360m/s^2)t^2]+(0.0190m/s^3)t^3. What is , the -component of the velocity

The position of a squirrel running in a park is given by r=[(0.280m/s)t+(0.0360m/s^2)t^2]+(0.0190m/s^3)t^3.What is , the -component of the velocity of the squirrel, as function of time?What is , the y-component of the velocity of the squirrel, as function of time?At 4.77 , how far is the squirrel from its initial position?At 4.77 , what is the magnitude of the squirrel's velocity?
