A Rocket is launched to travel vertically upwards with a constant velocity of 20 m/s. After travelling for 35 seconds rocket develops a snag and its fuel supply is cut off. The rocket then travels like a free body. What is the total height achieved by it? After what time of its launch will it come back to the earth? ( g= 10 m/s²⁾
