A car moves along a straight road. It moves at a speed of 50 km/hr for 4 minutes, then
during the next 4 minutes it gradually speeds up to 100 km/hr, continues at this speed
for 4 minutes, then takes 4 minutes to gradually slow to a complete stop. Make a
sketch like the figures in Section 1.2 of your textbook, marking dots for the position
along the road every minute.
What is the SI unit of instantaneous speed?
Select one:
O m/s.
m's
m.
O m/s.
To measure the instantaneous speed, what should be used?
Select one
O Two photogates only.
O One photogate + glider with double flag
O One photogate + glider with single flag
O Two photogates + glider with double flag
O Two gliders only
The average speed becomes a close approximation to the instantaneous speed when
Select one
O The distance between the two photogates is maximized
O The distance between the two photogates is reduced
O The air track surface is inclined
None of the offered choices fits
The triction is reduced
The minimum stopping distance for a car traveling at a speed of 30 m/sm/s is 60 m, including the distance traveled during the driver's reaction time of 0.50 ss .
What is the minimum stopping distance for the same car traveling at a speed of 47 m/sm/s ?
Express your answer to two significant figures and include the appropriate units.

- Imagine you are in charge of figuring out the maximum speed of a very foggy road. Consider a road that we cannot see anything beyond 15 meters. Suppose that human reaction time is 0.3s and the deceleration from pressing the brake is -10m/s². What should be the speed limit for this road in [m/s]? Hint: during the reaction time, the car still moves with constant speed. The car starts slowing down when the brake is pressed.arrow_forwardSuppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 60 km. What is the total end-to-end delay? Where is the last car in the caravan after one hour? Your answer must include a distance/specific location, and not only a relative direction.arrow_forwardA car starts from rest and accelerates at a constant 10 m/s2 during aquarter-mile (402 m) race. How fast is the car going at the finish line? I know the answer to this problem is 90 m/s, but I don't know how the book i found it in came to this answer. How am I supposed to solve this problem without knowing either final velocity or time?arrow_forward

When is her speed a maximum?arrow_forwardI did not understand this subject very well. (Average velocity, instantaneous velocity, average acceleration, instantaneous acceleration) And I am trying to understand with this question. Especially I can't get the "instantaneous" formulas in my head and I can't figure out why we did it. I would be happy if you could solve it in an explanatory way. Thanks.arrow_forward

- A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway?
