A 75 kg man and a 55 kg woman face each other on a skating rink, both wearing ice skates. The woman pushes the man with a horizontal force of 85 N in the positive x direction. a) What is the human acceleration? b) What is the reaction force acting on women? c) Calculate the acceleration of women. Third law, action is equal and opposite to reaction, even |F| 85 Newtons on both, positive on the man, negative on the woman.
F = my
a man = 85/75
a of woman = -85/55 a car with a mass of 100kg climbs a slope of 15 degrees with the horizontal.the engine of the car applies a force of 5000n the confficient of kinetic friction between the surface of the tyic and the road is of 0.2 . draw a diagram of the free body showing all the forces acting on the car. Ask your questions separately. not as an answer to someone else’s question. Under no circumstances can we provide you with diagrams.
Finally, the kinetic coefficient of friction does not apply to an object (like a car tire) that rolls without slipping. Perhaps the instructor is unaware of this.
The “force applied”, plus the weight, is the force exerted by the road on the tires.
