Circumference of a circle = 2πr
Circumference = 2π(2950 m) = 5900π m
Speed = 150 m/s
Time = Distance / Speed
Time = 5900π m / 150 m/s
Time = 118π/3 s = 123.57 s
How long does it take a plane, traveling at a constant speed of 150 m/s, to fly once around a...
A race car is traveling at a constant speed of 102 m/s around a circular track with a radius of 3250 m. How long does it take the race car to go around the track once? Express your answer in seconds.
1) A cyclist rides around a circle track with a constant speed of 8 m/s. If the radius of the track is 150 m then what acceleration does it experience? 2) A 75 kg tightrope walker is in the middle of the rope. The tightrope sags in the middle and creates a 30 degree angle below the horizontal. What is the tension in the cable? 3) A 0.75 kg yo-yo is spun around at a constant speed in a circle....
A biker runs at constant speed 34 m/s around a circular track with a centripetal acceleration of magnitude 12.5 m/s^2 a) what is track's radius ? b) what is the magnitude of angular velocity of the sprinter? c) what is the magnitude of the sprinter's angular acceleration? d) how long does it take to complete one revolution this time is called "period of motion"? e) how many revolutions per minute does the sprinter make?
A jetliner, traveling northward, is landing with a speed of 64.6 m/s. Once the jet touches down, it has 768 m of runway in which to reduce its speed to 14.6 m/s. Compute the average acceleration (magnitude and direction) of the plane during landing (take the direction of the plane's motion as positive).
A jetliner, traveling northward, is landing with a speed of 59.5 m/s. Once the jet touches down, it has 787 m of runway in which to reduce its speed to 5.75 m/s. Compute the average acceleration (magnitude and direction) of the plane during landing (take the direction of the plane's motion as positive).
A jetliner, traveling northward, is landing with a speed of 62.9 m/s. Once the jet touches down, it has 736 m of runway in which to reduce its speed to 11.1 m/s. Compute the average acceleration (magnitude and direction) of the plane during landing (take the direction of the plane's motion as positive).
Water flows through a 0.030-m-diameter hose at a speed of 4.0m/s. How long does it take to fill a container whose dimensions are 0.20mx0.30mx0.40m?
A car traveling at a constant speed of 29.0 m/s passes a trooper hidden behind a billboard. One second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 2.90 m/s2. How long does it take the trooper to overtake the speeding car?
A car travels at a constant speed around a circular track whose radius is 2.65 km. The car goes once around the track in 341 s. What is the magnitude of the centripetal acceleration of the car?
7 A bus is traveling east at a constant speed of 28 m/s. A car is 200 m behind the bus and begins to accelerate east at 4 m/s2 starting from an initial speed of 13 m/s. How long will it take the car to catch up to the bus?
