The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. At this rate, how many seconds would it take to swim 0.450 miles? (1 mi- 1609 m.) Number
The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. At this rate, how many seconds would it take to swim 0.300 miles (1 mi = 1609 m)? time:
A swimming pool is 50 m long and 20 m wide. Its depth decreases linearly along the length from 9 m to 1 m. It is initially empty and is tilled at a rate of 1 m^3/min. How fast is the water level rising 810 min after the filling begins? How long will it take to fill the pool? The water is rising at a rate of m/min 810 min after the filling begins. (Simplify your answer.)
An Olympic swimming pool is roughly 72 m long and 39 m wide. How long will it take to fill such a pool with an ordinary garden hose? Hint: You need to make a reasonable estimate for the depth of the pool and explain how you came up with an estimate. Estimate the flow rate for the garden hose in the same way. Do the necessary calculations and explain your result.
Jack and Jill exercise in a 25.0 m long swimming pool. Jack swims 9 lengths of the pool in 154.5 s (2 min and 34.5 s), whereas Jill, the faster swimmer, covers 10 lengths in the same time interval. Find the average velocity and average speed of each swimmer. Jack's average velocity: _______ m/s Jack's average speed: _______ m/s
Jack and Jill exercise in a 25.0 m long swimming pool. Jack swims 9 lengths of the pool in 152.7 s (2 min and 32.7 s) , whereas Jill, the faster swimmer, covers 10 lengths in the same time interval. Find the average velocity and average speed of each swimmer.
Jack and Jill exercise in a 25.0 m long swimming pool. Jack swims 9 lengths of the pool in 147.9 s (2 min and 27.9 s), whereas Jill, the faster swimmer, covers 10 lengths in the same time interval. Find the average velocity and average speed of cach swimmer. Jack's average velocity: m/s Jack's average speed: m/s Jill's average velocity: m/s Jill's average speed: m/s
Water at 20C in a D=10m, H=2m, above ground swimming pool is to be emptied by unplugging a 3-cm-diamater, 30-m-long horizontal plastic pipe attached to the bottom of the pool. Determine the initial rate of discharge of water through the pipe and the time it will take to fully empty the swimming pool assuming the entrance to the pipe is well-rounded with negligible loss. Use the initial discharge velocity to estimate the friction factor and use the factor for the...
In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of 177 mi/h. The one-way course was 8 mi long. Acceleration rates are often described by the time it takes to reach 60.0 mi/h from rest. If this time was 4.01 s, and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course (in...
The rate constant for this second-order reaction is 0.460 M–1·s–1 at 300 °C. How long (in seconds) would it take for the concentration of A to decrease from 0.630 M to 0.340 M?
