Answer» <p>total mass of body and plateform = 100kg</p><p>conservation of momentum in horizontal direction 100V + 110cos45 =0</p><p> V=-1/10√2 m/sec</p><p>negative sign indicates in the reverse direction.</p><p>time of filght = 210 sin 45 /10</p><p> = √2</p><p>so in this time plateform will move = Vt</p><p> =1/10√2 √2</p><p> = .1 m answer</p>
