The formula v = V2.3r models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvaturer, in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 470 feet. What is the maximum safe speed? For this problem, round your answer DOWN to the nearest whole number. (Think: Why is this type of rounding appropriate for this scenario?) max safe speed %D

A runner runs around a circular track. He completes one lap at a time of t = 292 s at a constant speed of v = 4.9 m/s What’s the radius, r in meters, of the track?
You're designing a highway so that the maximum centripetal acceleration on a curve is no more than 1.3 m/s^2. What is the minimum curvature radius to accommodate a 108 km//h maximum speed? This is about r=V^2/a, right? I have to convert km to meters, then hours to min to seconds. Say the final is (30m/s)^2 /1/3 m/s^2 =692.3 m Does two sig figs mean that 692 is changed to 690 m or something else to get two sig figs? Please explain? If the answer is 62.3 then two figs mean 62. If 63.5, then 64. But 692?
At the equator, the radius of the Earth is approximately 6370 km. A jet flies at a very low altitude at a constant speed of v = 245 m/s. Upon landing, the jet can produce an average deceleration of a = 15.5 m/s2. How long will it take the jet, in seconds, to circle the Earth at the equator? t = What is the numeric value for the minimum landing distance, d (in meters), this jet needs to come to rest? Assume that when the jet touches the ground it is moving at the same speed as it was when it was flying. d =

Suppose you went for a drive along a long, straight road that runs east-west. Let's define east to be the positive x direction. From your home, you drive east at 30. mi/hr to your friends house for 20. minutes, then at 48 mi/hr east for 10. minutes to the grocery store. Finally, you drive west at 60. mi/hr without stopping to get home. How many minutes will it take to drive from the grocery store to your home (at 60. mi/hr)? Note: Your answer should have the correct number of significant figures
