1.	C-2.A stone of mass 5 kg is thrown upwards with a speed of 36 misec With what speed earth recoil Massof the earths 61024 kg (assuming that there is no external force on the system)
Answer» <p>M= mass of stone = 5 Kgv= velocity of stone = 36 m/sM= mass of Earth = 610²⁴ KgV= velocity of EarthApplying Law of Conservation of Momentum , mv + MV = 0V= -mv/M = -(536)/6*10²⁴ = -3 × 10^-23Here , - sign indicates that direction of velocity of Earth is opposite to that of stone</p>
