A 125-pound person contains 57 kilograms of matter. a. What is their weight in newtons? Caution: always show your work; always include units, vector directions, and "-". signs. b. Is this weight the force that their scales push them, or the force that they push the scales with? C. Is the scale reading more/less/or the same (choose one), if the scale sits on an escalator moving upward at constant speed? Explain:

An old phrase used to sell cars was that they could "stop on a dime," meaning they could stop before the car moved a distance equal to the diameter of a dime. a. To see if this is realistic, calculate the net force needed to stop a 490-kg car moving at 25 miles/hour in a distance of 1.8 cm (the diameter of a dime). b. Compare that force to the weight of the car. Are they even close to the same size? Based on your comparison, is "stopping on a dime" a reasonable claim, or is the force needed unreasonably large? c. Calculate how much time it would take the car to stop. Is this a reasonable time for a car moving at 25 mph to stop, based on your experience traveling in cars?

Directions: Write TRUE is the statement is correct but if it is false, change the underlined words with the correct answer. 1. A force is a push or pull 2. Force is a galar quantity 3. The unit of force is Newton (N) 4. In general, a body can have several forces acting on it at the same time 5. Inertial frame of reference are reference frame where Newton's First law are observable. 6. Another effect of a balanced force, equilibrium, is that a body accelerates. 7. The heavier the object, the lesser the inertia. 8. Forces acting on a body are unbalanced if the resultant force is not zero 9. In an inertial reference frame, No forces should be exerted within the frame. 10. Normal force is lateral in nature. П.
