Question

A dog running in an open field has components of velocity vx = 2.6 m/s and vy = -1.8 m/s at time t1 = 10.4 s . For the time interval from t1 = 10.4 s to t2 = 24.8 s , the average acceleration of the dog has magnitude 0.49 m/s2 and direction 29.0 ∘ measured from the +x−axis toward the +y−axis.

Part A

At time t2 = 24.8 s , what is the x-component of the dog's velocity?

Express your answer using two significant figures.

Part B

At time t2 = 24.8 s , what is the y-component of the dog's velocity?

Express your answer using two significant figures.

Part C

What is the magnitude of the dog's velocity?

Express your answer using two significant figures.

Part D

What is the direction of the dog's velocity (measured from the +x−axis toward the +y−axis)?

Express your answer using two significant figures.
