Two balls are projected simultaneously with the same speed from the top of a tower, one vertically upwards and the other vertically downwards. If the first ball strikes the ground with speed \(20 \mathrm{~m} / \mathrm{s}\) then speed of second ball when it strikes the ground is  📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
