Find the time taken by stone dropped from a helicopter | 11th Class PHYSICS | CH # 3 | Numerical # 1

In this exciting physics experiment, we explore the principles of free fall and vertical motion. We use the second equation of motion to calculate the time it takes for a stone to reach the ground after being dropped from a helicopter ascending vertically at 19.6 m/s. Watch as we break down the problem step by step and provide a clear solution using basic physics concepts. In this video tutorial, I have solved the Numerical Problem # 1 of Chapter # 3 of 11th class physics. The problem statement of the numerical problem is: "A helicopter is ascending vertically at the rate of 19.6 ms-1. when it is at the height of 156.8 m above the ground, a stone is dropped. How long does the stone take to reach the ground?" I have started this question using "2nd equation of motion". I obtained a quadratic equation after putting and rearranging the data provided in the above problem statement. I have solved the quadratic equator using FACTORIZATION and I have also shown a way about how to use calculator to solve "2nd equation of motion". In the end, I also left a tricky question for you, which will blow your mind and you will start to think more practically. Watch the full video in order to grab the concept easily.
