Two billiard balls move toward each other on a table. the mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. the mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. after the balls collide, they bounce off each other. the number three ball moves off with a velocity of 5 m/s. what is the final velocity and direction of the eight ball? +8.6 m/s +6.0 m/s –6.0 m/s –8.6 m/s

The other answer is correct, however the answer on edg is +5.7

heats surface water up

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
