Bacteria move back and f01th by using their flagella (Structures that look like little tails). Speeds of up to 50m/s(50106m/s) have been observed. The total distance traveled by a bacterium is large for its size, while its displacement is small. Why is this?
(a) Use the distance and velocity data in Figure 3.64 to find the rate of expansion as a function of distance. (b) If you extrapolate back in time, how long ago would all of the galaxies have been at approximately the same position? The two parts of this problem give you some idea of how the Hubble constant for universal expansion and the time back to the Big Bang are determined, respectively. Figure 3.64 Five galaxies on a straight line, showing their distances and velocities relative to the Milky Way (MW) Galaxy. The distances are in millions of light years (Mly), where a light year is the distance light travels in one year. The velocities are nearly proportional to the distances. The sizes of the galaxies are greatly exaggerated; an average galaxy is about 0.1 MlY across.
An athlete crosses a 25-m-wide river by swimming perpendicular to the water current at a speed of 0.5 m/s relative to the water. He reaches the opposite side at a distance 40 m downstream from his starting point. How fast is the water in the river flowing with respect to the ground? What is the speed of the swimmer with respect to a friend at rest on the ground?
At some airports there are speed ramps to help passengers get from one place to another. A speed ramp is moving converyor belt on which you csan iether stand or walk. Suppose a speed ramp has a length of 117 m and is moving at a speed of 2.1 m/s relative to the ground. In addition, suppose you can cover this distance in 73 s when walking on the ground. If you walk at the same rate with respect to the speed ramp that you walk on the ground, how long does it take for you to travel the 117 m using the speed ramp?
Joey starts riding his scooter from his apartment to campus. He thinks it would be fun to make a graph ofhis position relative to time. By a weird coincidence, the graph is perfectly modeled by the equation 3t^2 -5t + 6 He tells his friend Andie that his average velocity for the second half of his trip was 39.2 units per timeinterval, because the slope formula says to do (256 - 60)/(5 -10) Is Joey correct?
You are arguing over a cell phone while trailing an unmarked police car by 25m; both your car and the police car are travelling at 120km/h. Your argument diverts your attention from the police car for 2.0s (long enough for you to look at the phone and yell, “I won’t do that!”). At the beginning of that 2.0s, the police officer begins braking suddenly at 5.05m/s^2. What is the separation between the two cars when your attention finally returns? Suppose that you take another 0.500s to realize your danger and begin braking. If you too brake at 5.05 m/s^2, what is your speed when you hit the police car?
Pep sees Kyle kick the football. 0.36 ?s later, he sees the lineman—who is standing 52 me away from Kyle—raise the offside flag. If Raheem observes these two events taking place at the same location, how fast must he be running?
A mischievous 1.1-meter boy stands on a bridge somewhere to drop a stone to passing cars. The height of the bridge is 6.2 meters and the distance between his head and shoulder is 10.0 inches. He drops the stone with his arm positioned horizontal to his shoulder while the car was 7.1 meters away. What must have been the velocity of the car if the stone hit it with a perfect timing?
Two triggers, 20 feet apart, activate when a car's tires run over them. The time between the two signals is 0.4 seconds. 1) Calculate the speed of the car in mph. (This may speed your conversion: 88 ft/s = 60 mph.) 2) how might someone evade the speed trap, if he spots it just as he's about to hit the first signal?
A jet plane is observed 400ft above the ground and is flying 180mph tothe west. A man jumps out of the plane creating a projectile motion and recordedthat he is descending at a constant velocity of 6 ft/s after he reached an observabledistance from the ground. If the man is to reach the ground 37 seconds after hisimmediate jump off the plane, determine the range from the initial position of theplane to the target landing of the man in the ground.
