Question

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?

Answer 1

your answer is gonna be a velocity decreas of 10 meters per second

Answer 2

Answer:

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

$\Delta v=-10\ m/s-20\ m/s=-30\ m/s$

Hence, this is the required solution.
