The platform with an attached gun is moving with velocity of 9 km/h. The total mass M of gun and the platform is 200m (including the bullet). From the gun bullet of mass m was fired at a speed of 800 m/s relative to the platform. Determine the speed of the platform after the shot, if the shot is made at an angle = 60° to the direction of motion. (A) 0.4 m/s (B) 0.3 m/s (C) 0.2m/s (D) 0.5m/s एक प्लेटफॉर्म से एक गन जुड़ी हुई है तथा यह 9 km/h वेग से गतिशील है। गन तथा प्लेटफॉर्म का कुल द्रव्यमान (गोली सहित) M का मान 200 m है। गन से द्रव्यमान m वाली गोली को प्लेटफॉर्म के सापेक्ष 800 m/s चाल से दागा गया था। गोली दागने के बाद प्लेटफॉर्म की चाल ज्ञात कीजिये, यदि गोली गति की दिशा से 60° कोण बनाते
