## Homework Statement

A ball is dropped from a balloon going up at a speed of 7 m/s. If the balloon was at a height 60 m at the time of dropping the ball, how long will the ball take to reach the ground?

__Ans:4.3 seconds__## Homework Equations

## The Attempt at a Solution

**I can't understand the question**.

Is the initial velocity of the ball when it is dropped=0? or is it 7m/s.

What value should I take for g? Should I take g= 9.8 m/s[itex]^2[/itex]?

Please help me. I assumed ball is dropped from 60 m height with initial velocity=0 and a=g=9.8 m/s[itex]^2[/itex]. But it gives wrong answer. What is the concept of this question? How to solve it?
