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?
-30 m/s



-10 m/s



10 m/s



30 m/s

Answer 1

change in velocity = v - u 

u = 20 m/s 

v = - 10 m/s 

v - u = -10 - 20 = -30 m/s 

Answer 2

-30 m/s is the change in velocity of the coconut.

Explanation:

Given,

The initial velocity of the flying coconut = 20 i^             (∵ It moves in +ve direction)

The final velocity of the flying coconut = -10 i^               (∵ It moves in opposite direction)

As we know,

Change in velocity = Final velocity - Initial velocity

so,

Change in velocity = -10 i^ - 20 i^

= -30 i^

Thus, -30 m/s is the change in velocity of the flying coconut.
