Sobre un cuerpo de 10Kp colocado sobre un plano horizontal actúa una fuerza de 12Kp, la cual forma con la horizontal un ángulo de 30°. Si el cuerpo se mueve con velocidad constante y no se considera la fricción. Calcular el trabajo realizado por la fuerza al moverse 8m.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

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

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
