Since the man on the motorcycle was riding at a fast speed and he braked he flew off of the motorcycle and will travel on forever until stopped by another force.
Newton's 1st Law.......An object in motion stays in motion, an object at rest stays at rest unless acted upon by another force.
Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's second Law, you can compute how much force Mike is applying to the car. F=1,000x0.05. Answer: 50 newtons
Newton's 2nd Law.......The acceleration of an object as produced by a net force is directly proportional to the magnitude as the net force, and inversely proportional to the mass of the object
Since both of the people are pushing against each other they are going to go the opposite way
Newton's 3rd Law......Forces always occur in pairs. Forces in a force pair do not act on the same object (Do not cancel each other). Equal forces do not always have equal effects.
