Question

An arrow in flight has an initial velocity of 65 meters per second, and 10 seconds later, it has a velocity of 35 meters per second. Which is the acceleration of the arrow?

Answer 1

To find the acceleration, we would need to use the equation acceleration= final velocity- initial velocity/elapsed time. Since the final velocity is 35 and the initial velocity is 65, we can subtract 65 from 35 first, which gives us -30. Then if we divide that by the elapsed time, which is 10, we get -3. Your acceleration is -3 meters per second.

Hope this helps! :D
