(5) The answers are rounded off. Choose the closest to exact. There is no penalty for guessing. (6) Hand in the answer sheet separately. Constants: G = 6 . 67 × 10- 11 N m 2 /kg 2 g = 9 . 80 m/s 2 1. An object with mass 0.10 kg is attached to a spring with spring constant 200 N/m. The object oscillates about the equilibrium position with an amplitude of 3.0 cm. Find the maximum velocity of the object. (1) 1.3 m/s (2) 60 m/s (3) 4.2 m/s (4) 27 m/s (5) 0.24 m/s 2. An object with mass 0.15 kg is attached to a spring with spring constant 100 N/m. The object oscillates about the equilibrium position with an amplitude of 3.0 cm. Find the maximum velocity of the object. (1) 0.77 m/s (2) 20 m/s (3) 11 m/s (4) 3.9 m/s (5) 0.14 m/s 3. An object with mass 0.20 kg is attached to a spring with spring constant 100 N/m. The object oscillates about the equilibrium position with an amplitude of 4.0 cm. Find the maximum velocity of the object. (1) 0.89 m/s (2) 20 m/s (3) 13 m/s (4) 4.1 m/s (5) 0.24 m/s 4. An airplane emits sound of frequency of 4500 Hz. The airplane travels at a speed of 240 m/s. To a stationary listener behind the plane, what is the frequency of the sound? Given that the speed of sound is 340 m/s. (1) 2640 Hz (2) 15300 Hz (3) 1320 Hz (4) 7680 Hz (5) 3180 Hz 5. An airplane emits sound of frequency of 2400 Hz. The airplane travels at a speed of 260 m/s. To a stationary listener behind the plane, what is the frequency of the sound? Given that the speed of sound is 340 m/s. (1) 1360 Hz (2) 10200 Hz (3) 4240 Hz (4) 5650 Hz (5) 1840 Hz 6. An airplane emits sound of frequency of 3100 Hz. The airplane travels at a speed of 270 m/s. To a stationary listener behind the plane, what is the frequency of the sound? Given that the speed of sound is 340 m/s....
