When a ball is dropped into a lake from a height \(4.9 m\) above the water level, it hits the water with a velocity \(v\) and then sinks to the bottom with the constant velocity v. It reaches the bottom of the lake \(4.0 s\) after it is dropped. The approximate depth of the lake is: 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
