1. The problem statement, all variables and given/known data A person stands on a scale on an elevator. If the mass of the person is 96.34 kg and the elevator travels upward at a constant speed of 4.42 m/s, what is the reading on the scale? 2. Relevant equations m = 96.34 kg V avg = 4.42 m/s 3. The attempt at a solution I think what this is asking for is the weight of the person, the force exerted on the scale by the person. So if the velocity is constant, wouldn't the acceleration be 0? So F = ma = 0. I don't know if that's right? 1. The problem statement, all variables and given/known data Two horizontal forces act on a 1.7 kg mass. One force has a magnitude of 9.78 N and is directed due north. The second force toward the east has a magnitude of 1.48 N. What is the magnitude of the acceleration of the mass? 2. Relevant equations 3. The attempt at a solution I don't know how to go about solving this.
