13. It takes 70 lbs of force to start a 100 lb object sliding along a level surface.
14. It takes 28 lb of force to start a 37 lb object sliding along a level surface.
15. It takes 4.9 N of force to start a 1 kg object sliding along a level surface.
16. It takes 9.3 N of force to start a 1 kg object sliding along a level surface.
1. How much does 40 ms between pulses reduce the likelihood of winning a round
2. How much advantage does a SumoBot with a payload that increases its mass to

compared to 20 ms between pulses. Start by adjusting the plows so that each
SumoBot gets the advantage in 5 out of 10 trials. You may want to repeat 20 or
30 trials to be sure the odds are close to 50/50.
Modify Forward100Pulses.bs2 so that the SumoBots' servos turn indefinitely.
The trial should then be run long enough to give you a clear idea of which
SumoBot will win the round. You will want to see one SumoBot obviously
losing ground and getting pushed backwards by the other.
Modify a second version of Forward100Pulses.bs2 so that it runs indefinitely
with 40 ms pause times instead of 20 ms pause times. Repeat another 30 trials.
How many times did the SumoBot with 20 ms
significant or negligible increase?
500 g have over a SumoBot with no payload? As with Project 1, start with two
SumoBots that are equally matched for gaining plow advantage.
Forward100Pulses.bs2 in each SumoBot. This time, the programs should have
identical PAUSE durations. Add a payload to one of the SumoBots to increase
its mass to about 500 g. Repeat 30 trials and compare to the initial advantage.
How many times did the SumoBot with more mass win? Again, is this a
significant or negligible increase.
