Part A: Multiple Choice

1)A grandfather clock measures time by counting the num­ber of oscillations of a small-angle pendulum. You take a grandfather clock that gives the correct time at sea level (where g =9.81 m/s²) up a mountain and notice that after two days it is running five minutes behind. What is the value of the gravitational acceleration up that mountain?

1.  9.74 m/s²
2. 9.78 m/s²
3. 9.84 m/s²
4. 9.81 m/s²
5. There is not enough information to answer the ques­tion

2)The Hubble space telescope, having a mass of 11 110 kg, is in low-Earth orbit with a semi-major axis of 6 924 km. What is its orbital period?

1. 95.6 minutes
2. 3.02 × 10⁻³ minutes
3. 2.22 × 10¹² minutes
4. 136 minutes
5. 15.2 minutes

3)A 75 kg person gets in an elevator. How much more power must the elevator’s motor supply if the elevator is to go up at the same constant speed of 0.5 m/s as it goes up when empty？

1. 221 W
2. 552 W
3. 1470 W
4. 368 W
5. 92.0 W

4)A 2 kg ball is initially stationary on a flat, frictionless surface. It is then hit by a 0.25 kg piece of putty travel­ing at 25 m/s. After the collision, the putty sticks to the ball. At what speed will the putty-covered ball travel?

1. 8.83 m/s
2. 2.78 m/s
3. 22.2 m/s
4. 3.13 m/s
5. 8.33 m/s

5)You are holding a bottle of pop in your hands on a bus. The bubbles in the pop are going straight up. Suddenly, the bus brakes hard to avoid a road hazard. How is the motion of the bubbles in the pop affected?

1. The bubbles will gain some motion towards the front of the bus.
2. The answer depends on the initial speed of the bus.
3. The motion of the bubbles will not change.
4. The bubbles will gain some motion towards the back of the bus.
