In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .
A surveyor measures the distance across a straight river by the following method: starting directly across from a tree on the opposite bank, he walks x = 1.00 102 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline lo the tree is = 35.0 (Fig. P1.53). How wide is the river? Figure P1.53
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?

Bill and Amy want to ride their bikes from their neighborhood to school which is 14.4 kilometers away. It takes Amy 40 minutes to arrive at school. Bill arrives 20 minutes after Amy. How much faster (in meters/second) is Amy's average speed for the entire trip? Be sure to show all necessary metric conversions!!

It was an epic 1/4 mile race. Car 1 finished at 6.66.00s. Car 2 finished at 6.66.20s. How fast was the winning car going at the end of the race? Give your answer in m/s (meters per second). b) What was the acceleration of the winning car? Give your answer in m/s2 (meters per second squared).

Coyote happens to be chasing after the Roadrunner, who is traveling in the +x-direction with a constant velocity of 8.72 m/s. Wile E. Coyote has a velocity of +3.28 m/s and a constant acceleration of +2.30 m/s? at the moment it is 10.0 m behind the Roadrunner. Take the initial position of the Roadrunner to be the origin (x = 0). a) time. Hint: Your answer should look like xR = fR(t). Express the final position of the Roadrunner (with respect to the origin) as a function of b) time. Hint: Again, your answer should look like xc = Express the final position of Wile E. Coyote (with respect to the origin) as a function of fc(t). c) use the quadratic formula here, you should get two times. Consider which one, if both, of these times makes sense in the context of this problem. How much time elapses before Wile E. Coyote catches the…
