Una fuerza de 60N arrastra un bloque de 300N mediante una cuerda a un ángulo de 40° sobre una superficie horizontal uk: 0.2 ¿Qué fuerza P producirá rapidez constante? Con una explicación por favor :(

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
