Answer:
R = 8.01 m
Explanation:
We can solve this problem using the projectile launch equations. The jump length is the throw range
R = v₀² sin 2θ / g
in the exercise they give us the initial speed of 9.14 m / s and in the launch angle 35º
let's calculate
R = 9.14² sin (2 35) / 9.8
R = 8.01 m
this is the jump length
178 centimeters is exactly, precisely, the same length as ...
-- 0.00178 kilometer
-- 1.78 meters
-- 1,780 millimeters
-- 1,780,000 micrometers
-- 1,780,000,000 nanometers
The material that transmits most light is d) clear glass.
Explanation:
Depending on whether objects can transmit light or not, they can be classified into three types:
- Opaque: an object opaque does not transmit light at all (light cannot pass through an opaque object). Examples of opaque objects are metals
- Translucent: translucent objects allow light to pass partially through them. Examples of translucent objects are fluids
- Transparent: transparent objects allow light to pass through them. An example of transparent objects is clear glass
In this problem, we have the following objects:
- Umbrella: it is opaque, light does not pass through it
- Blanket: it is opaque, light does not pass through it
- Mirror: It is opaque, since it reflects light (light does not pass through it)
- Clear glass: it is a transparent object
Therefore, the material that transmits most light is d) clear glass.

Answer:
The answer is ( D) i. e both b and c.
<span>2) s(t) = 155tcos(23°) </span>
<span>=> s(1.4) = 155 * 1.4 * cos(23°) </span>
<span>=> s(1.4) ≈ 199.7 ft (1 dp) <=- distance displaced horizontally </span>
<span>a(t) = -32 ft/s^2 </span>
<span>=> v(t) = -32t + 155sin(23°) </span>
<span>=> h(t) = -16t^2 + 155tsin(23°) </span>
<span>=> h(1.4) = -16(1.4)^2 + 155(1.4)sin(23°) </span>
<span>=> h(1.4) ≈ 53.4 ft (1 dp) <== distance displaced vertically.</span>
