KE gets converted to Q, thermal energy KE = 1/2*m*v^2 Q = KE, assuming complete conversion to thermal energy. Thus Q = 1/2*m*v^2 Data: m:=1050 kg; v:=250/9 meters/sec; Result: Q = 405093...

You know the linear speed and the mass of the ball so you know the translational kinetic energy, Kt Kt = 1/2 mv^2 = 50.54 J Now to get he rotational energy Kr, you need the moment of inertia of a solid sphere taken aroun its center, and the rotational speed of the ball...

Note that, after t seconds, the boat travels 1.65t m towards the short and the boat floats 1.05t m down stream. Then, the distance that the boat actually travels is: D = √[(1.65t)^2 + (1.05t)^2] = 1.96t. Therefore, the
