Answer:
A. 1 in³ / 16.4 cm³
Explanation:
Inches is an imperial unit while centimeter is a metric unit.
1 inch = 2.54 cm
⇒1 inch³ = 2.54³
⇒1 inch³ = 2.54×2.54×2.54
⇒1 inch³ = 16.38 cm³ = 16.38 cc
So,
So, 1 in³ / 16.4 cm³ conversion factor should be used.
Answer:
Cause, The thickness of the windshield formed between the glass and the lens is zero.
Answer:
0.03 s
Explanation:
The maximum force is 90 N, and the mass is 0.2 kg, so we can find the deceleration:
F = ma
-90 N = (0.2 kg) a
a = -450 m/s²
The initial velocity is 14 m/s, and the final velocity is 0 m/s, so the time is:
v = at + v₀
0 m/s = (-450 m/s²) t + 14 m/s
t = 0.03 s
The fastest she can slow it down to a stop without breaking it is in 0.03 s.
