4) You do 200 J of work in 61 seconds, and your friend does the same work in 1 minute. It follows that your friend is more powerful than you are(T,F)
Homework Answers
W = 200 Joule
t1 = 61s and t2 = 1mint = 60s
P1 = 200/61 = 3.278
P2 = 200/60 = 3.334
=) P2 > P1
That means my friend is more powerful than me. Hence statement is true .

Your friend believes that he has found a route to work that would make your commute faster than what it currently is, under similar conditions. To test this claim, you and your friend time the commute from your house to the building where you work over a random set of days, and you flip a coin each day to determine who takes which route. Each trip is done at the exact same time of day. Find the test statistic and...
