Answer:
Watermelon is going at a speed of in downward direction
Explanation:
Given
- Height of the Empire State building = 320 m
- Speed of the superman = 24 m/s
since both the motion of both watermelon and the superman is under gravity. The acceleration of both is g in downwards direction. So the relative acceleration between them is zero and when they meet the relative distance covered by them will be the height of the Empire State building.
so let t be the time when they meet given by
Now let v be the velocity of the the watermelon when they meet given by
