a > 10. The components of vectors A and B are given as follows: Ax = 7.6 Bx = -5.'l Ay = -9.2 By = -6.8 > > What is the magnitude of the vector difference B A ? 3. You want to store 1,000 J of energy in an ideal spring when it is compressed by only 2.5 cm. What should be the force constant (spring constant) of this spring?8. A frictionless simple pendulum, with a small but dense 4.4-kg mass at the end and a length of 75 cm, is released from rest at an angle of 50 with the vertical. (a) To what height above its lowest point does the mass swing on the other side? (b) What is the speed of the mass at the bottom of the swing? B i U Font Family AA A 9. A very light ideal spring having a spring constant (force constant) of 8.2 N/cm is used to lift a 2.2-kg tool with an upward acceleration of 3.25 m/s2. If the spring has negligible length when it us not stretched, how long is it while it is pulling the tool upward?13. How high a hill would a 75-kg hiker have to climb to increase her gravitational potential energy by 10,000 J? B i U Font Family - AA A 9 14. How fast must a 6.0-kg cat run to have a kinetic energy of 150 J? B i U Font Family AAA DE EE
