Check Your Understanding A high school track coach has just purchased a new stopwatch. The stopwatch manual states the stopwatch has an uncertainty of ±0.05 s. Runners on the track coach’s learn regularly clock 100-rn sprints of 11.49 s to 15.01 s. At the school’s last track meet, the first-place sprinter came in at 12.04 s and the second-place sprinter came in a 12.07 s. Will the coach’s new stopwatch be helpful in timing the sprint team? Why or why not?

According to Timothy Treadwell in 2001 "Now, the bears I live with average, the
males are on average twelve hundred pounds. They're the largest bears in the
world and they've been clocked at 41 [mph] and they've run a hundred meter
dash in 5.85 seconds which human on stimulants doesn't even approach.
a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter
statement.
b. Compute the momentum of a grizzly bear using the speed you calculated in
part a. and the average mass stated by Mr. Treadwell.
c. How fast would a 250 lb man have to run to have the same momentum you
calculated in part b?
d. How fast would a 4000 lb car have to drive to have the same momentum you
calculated in part b?
a) A robin flies a distance of 45 963 cm. How far has it flown in kilometres?(b) What is the speed in metres per second of a car that is travelling at 82 km/h? (c) What is the speed in kilometres per hour of a 27.78 m/s baseball pitch?(d) How many seconds are there in a calendar year, given that a calendar year has 365.24 days in it? T/I
