The minimum dimensions for the rear-view mirror should be a height of 0.890 m and a width of 1.3 m.
In order for the driver to be able to see the entire width and height of the rear window in the rear-view mirror without moving their head, the mirror should have minimum dimensions that allow for this visibility. Let's calculate the minimum height and width required for the rear-view mirror.
Height of the mirror:The mirror should be half the height of the driver, which is given as 1.715 m at the top and 0.825 m at the bottom. Therefore, the height of the mirror should be 0.890 m (1.715 m - 0.825 m).Width of the mirror:The mirror should be wide enough to capture the entire width of the rear window. The width of the rear window is given as 1.3 m, so the width of the mirror should be at least 1.3 m. Therefore, the minimum dimensions of the rear-view mirror should be a height of 0.890 m and a width of 1.3 m.#SPJ12

Answer:
Decrease the friction between the wheels and the track.
Explanation:
Decrease the friction between the wheels and the track. Friction opposes motion. If the amount of friction is decreased, the speed of the cars should increase.

Answer: 5.9 m/s
Explanation:
This problem can be solved by the Conservation of Momentum principle, which establishes that the initial momentum must be equal to the final momentum :
(1)
Where:
(2)
(3)
is the mass of the skater
is the mass of the ball
is the initial velocity of the skater and the ball
is the final velocity of the ball
is the final velocity of the skater
Substituting (2) and (3) in (1):
(4)
Isolating :
(5)
(6)
Finally:
