1. One stone is dropped from the top of a tall cliff, and a second stone with the same mass is thrown with a velocity of 12 m/s straight down from the same cliff, 5T 1 s after the first rock is dropped. Calculate the distance below the top of the cliff 1C at which the second stone overtakes the first.2. An airplane has a velocity of 500 kmr'h relative to the moving air. At the same time, a wind blows [E3008] with a speed of 90 kah relative to Earth. The 4T airplane is moving in an easterly direction relative to Earth. Find the velocity of 1C the airplane relative to Earth
