  11. Open Ended Questions • 1. • 2. V = IR = 10 x 7 = 70 V • 3. I = V/R = (7x1.5)/5 = 2.1 A • 4. I = P/V = 90/(4x1.5) = 15A • 5. V = P/I = 3400/18 = 188.8 V • 6. W = Fxd = 100 x 1 = 100 J

  12. 7. P = W/t = 1500 / 30 = 50 W • 8. To lift the first object, the kinetic energy is ½ 2kg x 22=4 J To lift the second object, the kinetic energy is ½ 4kg x 32=18 J Therefore, the second object has more kinetic energy.

  13. 9. The potential energy for the first object is mgh = 2 x 9.8 x 10 = 196 J • The potential energy for the first object is mgh = 4 x 9.8 x 10 = 392 J Therefore, the second object has more potential energy.

  14. Corrections • 10. Calculate the momentum of a 100-kg football player, a fullback, moving at a velocity of 3.5 m/sec. • Momentum = mass x velocity = 100 x 3.5 = 3500 kg m/sec

  15. 10b. Calculate the acceleration of a 10 kg mass when a 40 N force is applied to it. • Acceleration = F/m = 40/10 = 4 m/s2

  16. 11. Thickness of one business card is 1.95 cm / 62 = 0.031 cm • 12. Mass of one staple is 7.2 g / 323 = 0.02 g
