3. How far can you get away from your little brother with a squirt gun filled with ice cold water if you can travel at 3m/s and you have 12 seconds before he sees you?
The activity: Fold the sheets of bond paper length-wise and tape them on the floor to make a track for the toy car. Make the track long enough for the toy car to travel 100 cm. Flick or push the toy car with you finger to send it moving along the track and measure the timeit takes to travel 100 cm. In the first activity, does it matter if the floor where you made the track for the toy car is level or not? a . No, because in the activity, the speed of the toy car is constant. b . Yes, because if the floor was not level, gravity would have an influence on the motion of the toy car. c . No, because the activity is looking at the relationship between total distance traveled and elapse time. d . No, because the motion of the toy car will only depend on the flick or push strength that was used
The great astronomer Edwin Hubble discovered that all distant galaxies are receding from our Milky Way Galaxy with velocities proportional to their distances. It appears to an observer on the Earth that we are at the center of an expanding universe. The figure illustrates this for five galaxies lying along a straight line, with the Milky Way Galaxy at the center. B) Using the data from the figure, calculate the velocity of galaxy 3 relative to galaxy 2 in km/s. C) Using the data from the figure, calculate the velocity of galaxy 4 relative to galaxy 2 in km/s. D) Using the data from the figure, calculate the velocity of galaxy 5 relative to galaxy 2 in km/s. E) Using the data from the figure, calculate the velocity of galaxy 1 relative to galaxy 5 in km/s. F) Using the data from the figure, calculate the velocity of galaxy 2 relative to galaxy 5 in km/s. G) Using the data from the figure, calculate the velocity of galaxy 3 relative to galaxy 5 in km/s. H) Using the data…
The motion of a cart can be represented by x(t)=(-2.5m/s)t-10.0m. At what time does this cart cross the origin? a)it crosses the origin t=4s after we start observing it b)It crosses the origin t=0s after we start observing it c)If it were moving the same way before we started observing it then it crossed the origin 4 seconds before we started counting.
F 12 1. Motion Diagram An airplane is taking off. Its positions at 12 moments, each separated from the next by exactly 40 seconds, are indicated in the figure. Notice that each grey box corresponds to 1500 meters of real-life distance. 3 5 6 Fo Co 3000m 9 10 Summarize briefly how the speed of the airplane varies between moments 1 and 12. (b) What is the direction of the airplane's displacement in the 6→7 time interval? What is the magnitude of the airplane's average velocity in the 8-9 interval? 11 12

AE 5m XI -5 m 5 m FIG. 2.10 A spacetime diagram showing the worldlines of various particles. P2.1 The spacetime diagram in figure 2.10 shows the worldlines of various particles moving along the x axis in space. Note that (as is conventional in spacetime dia- grams), I have calibrated the r and x axes in this diagram. to have the same scales in the same units: this ensures that the worldline of a photon (which has a speed of 1) makes a 45° angle with each axis. For each labeled world- line, describe (1) where the particle is at time t = 0, (2) about how fast and in what direction (in the +x direction or the-x direction) the particle is moving at that time, and (3) whether the particle's speed subsequently increases or decreases as time passes. Also identify the one worldline that is physically impossible, and explain why.
