2. A 2.5 N horizontal force is applied to a 10 N pendulum bob, subtending it by an angle from the vertical, as shown below. What is the tension in the string? (neglect the mass of the string) N 3. What is the force the floor exerts on a person who is in an elevator that's accelerating upward at 1.5 m/s²? The mass of the person is 75 kg. Draw a free body diagram of the person in your solution.
