In a video game, a flying coconut moves at a constant velocity of 20 meters/second. the coconut hits an obstacle and moves in the opposite direction with a constant velocity of 10 meters/second. what’s the change in velocity of the coconut?

Change in velocity of the coconut = -30 m/s                

Explanation:

It is given that,

In a video game, a flying coconut moves at a constant velocity of 20 meters/second i.e. initial velocity, u = 20 m/s

The coconut hits an obstacle and moves in the opposite direction with a constant velocity of 10 meters/second i.e. final velocity, v = -10 m/s ( opposite direction )

Change in velocity of the coconut = final velocity - initial velocity

Hence, this is the required solution.

answer; i believe that the correct answer is (d) a very small amount of mass
