A physics student whirls a rubber stopper around in a horizontal circle. Suddenly the string breaks. What is the speed of the rubber stopper the moment the string breaks if the radius of the circle is 0.75 m, the mass of the stopper is 45 grams, the angle θ in the diagram is 30 degrees, and the counter weight is 100 grams? Use g = 10 m/s^2.

the answer is to check all of them! they all apply well at least i think so!

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
