1. How much does a ball which has a mass of 1009 weigh on Earth? How about Jupiter? Which direction do the forces point when the ball is on a at surface on each planet? (97 of Jupiter is 24.58m/s2) (Watch out for sig. gs. and units). 2. You have a force approximately 20N pointing in the +3: direction, What happens when you introduce a second force ION (pointing in the +3: direction) and have it act on the rst force? 3. What forces does a force table tend to read?(specically for this experi- ment) 4. Refer to the diagram below, if A = ION and B = 4N , what is the Net Force and which direction does it point. 39
