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.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.
