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?

Explanation:

Given that,

Initial velocity of arrow, u = 65 m/s

Final velocity of arrow, v = 35 m/s

Time taken, t = 10 seconds

The acceleration of the arrow is given by the rate of change of velocity per unit time. It is given by :

The arrow in flight is decelerating. Hence, this is the required solution.

all of the answers are correct.
