A bird is flying north at 5 m/s. The bird veers and travels at 5 m/s east. This happens over a 2 second period. what is the average acceleration (magnitude and direction) during this 2 second interval?
 
Physics news on Phys.org
It is vector subtraction problem. Find (V2 - V1) and divide it by t.
 
correct me if I am wrong but is the answer 5? I am not sure
 
V1 is towards north, v2 is towards east. - v1 is towards south. V1 and V2 are at right angle to each other. There fore magnitude of the change in velocity is sqrt(V1^2 + V2^2)
 
So the average acceleration is 3.53m/s/s Yes?
 
Yes.
