A person in the passenger basket of a hot-air balloon throws a ball horizontally outward from the basket with a speed of 10.0 m/s. What initial velocity (magnitude and direction) does the ball have relative to a person standing on the ground if the hot-air balloon is rising at 6.0 m/s relative to the ground during this throw?

Explanation:

Given

balloon is rising with a speed of

Person throws a ball out of basket with a horizontal velocity of

Considering upward direction to be positive

When ball is thrown it has two velocity i.e. in upward direction and in horizontal direction so net velocity is

Direction of velocity

where is angle made by net velocity with horizontal .

answer: f

explanation: g

answer; i believe that the correct answer is (d) a very small amount of mass
