Well, we're going to need a little more information. The heat capacity or sometimes referred to as the specific heat, for the aluminum and water
Mass x heat capacity x ( T1 - T2) = Heat transfered. Since the heat is transfered between the water and aluminum it results in the following
Mass x heat capacity x (temp change aluminum) = mass x heatcapcity x (temp change water )
You also know that the final temperature of the water and aluminum will be the same.

even as bag is released from balloon then it extremely is going to pass with the same speed 3 m/s in upward route. Now, initial speed u = + 3m/s ( up route ) information superhighway displacement = -- 9.5 m ( downward ) acceleration = g = -- 9.8 m/s^2 (downward) s = ut + a million/2 at^2 - 9.5 = 3t + a million/2 x (-9.8) x t^2 4.9 t^2 - 3t - 9.5 = 0 after fixing this quadratic equation effectual fee of time t = a million.7 sec answer
