Homework # 25 -Weight Handout Problems: 1. A force applied to a rocket gives it acceleration equal to 2 g. The same force applied to a second rocket gives it acceleration equal to 6 g. Compare the masses of the two rockets. Note: g = 9.8 mlsz. A SOD-N girl standing on a bathroom scale jumps upward. Why does the scale read more than 500 N at the moment she jumps? (3) What is the weight of a 10-kg piece of iron? (b) What is the mass of an object that weighs 490 N? An 8.0-kg rocket red horizontally encounters a force of air resistance of 4.9 N. The force of the rocket's engine is 60.9 N. (a) What is the net force accelerating the rocket? (b) What is the acceleration of the rocket? A model rocket weighs 196 N. (a) What is its mass in kilograms? (b) If the engine of the rocket can exert an upward force of 276 N, then what will the acceleration of the rocket be? Neglect air resistance. A "ISO-N fellow stands on a bathroom scale in an elevator. What will the scale read while the elevator is (a) descending at constant speed; (b) descending with half the acceleration of gravity
