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...

first calculate the time it took for sound to travel 45m v = d/t so t = d/v t = 45/330 t = .13636 secs subtract this time from the total time t = 1.45989 - .13636 t = 1.32353 secs last, using the remaining time, find the average velocity of the thrown ball v = d/t v = 45/1.32353 v = 34 m...

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...

v = A sqrt(k/m) f ~ sqrt(k/m), so if the frequency is doubled, the max speed is doubled.

(a) by the amount of time it takes to fill the bucket: 22 L / 96 seconds = 0.23 Liters (equal to 230 cm^3) coming out of the hose every second. We think of the water coming out of the hose as as cylinder with length L, surface area A and volume V...

Since initial velocity is 34.8 and final velocity is 25 the change is 9.8 and time is 3.5 so magnitude is 9.8/3.5 and direction is to west as slowing down b)can be caluculated by s=ut+1/2at^2

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

**spe**ed of the boat is: v...2 Answers · Science & Mathematics · 18/02/2011
