Part A: Multiple Choice

1)Two astronauts, each of mass 75kg, are floating next to each other in space, outside the space shuttle. One of them pushed the other through a distance of 1m( an arm's length) with a force of 300N. What is the final relative velocity of the two?

2. 2.83m/s
3. 4.0m/s
4. 16.0m/s

2)Twelve identical resistors(each of resistance R) are placed along the 12 edges of a cube. What is the effective resistance between opposite corners of the cube?

1. 12R/3
2. 5R/6
3. R
4. 12R

3)A heavy wooden beam of length L lies on the ground. You must carry it with a friend o happens to be twice as strong as you are(she can carry twice as much weight with the same effort). If you pick up the beam at one? end, at what distance from your end should your friend carry it in order to be fair?

2. 3L/5
3. 3L/4
4. L

4)A car travelling at 80km/h needs a braking distance of 50m to come to a complete stop. What braking distance should at the same car need if its initial speed were 160km/h? You ma assume that the same braking force can be applied in both cases.
