The temperature of 100 g of water is to be raised from 24?C to 90?C by adding steam to it. The mass of the steam required for this purpose is
A cannon ball is fired with a velocity ${200\, m \, s^{-1}}$ at an angle of 60? with the horizontal. At the highest point of its flight, it explodes into 3 equal fragments, one falling vertically downwards with a velocity ${100\, m\, s^{-1}}$. The second is going vertically upwards with a velocity ${100\, m\, s^{-1}}$, the third fragment will be moving with the velocity
