Question

Suppose a bird takes off from a tree and flies in a straight line. It reaches a speed of 1o miles per second. What is the change in the bird's velocity?

Answer 1

10miles/second

Step-by-step explanation:

Change in velocity of the bird is expressed as the difference between the final velocity and initial velocity of the body.

Change in velocity = Final velocity - initial velocity

Since the bird takes off from the tree, the initial velocity of the bird = 0miles/sec

Final velocity = 10miles/secs

Change in velocity = 10-0

Change in velocity = 10miles/second
