The answer to ur question is: B
Using kinematic equation, v =u +at, u= v-at = 20- 3x5 = 5m/s. Initial velocity = 5 m/s
<span>The sun is currently a hot ball of glowing gases that is considered as a star. It is the center of our solar system. Its power is responsible for bringing life to this planet and it also affects the orbits of distant planets like Neptune and Pluto. Without it, Earth will not have the capacity to sustain life and maintain its balance.<span>
