Aboy threw a small bundle toward his girlfriend on a balcony 10. meters above him. the bundle stopped rising in 1.5 seconds. how high did the bundle travel? was that high enough for her to catch it?

Hi!

We know that the boy must have thrown the bundle with some initial velocity 'v', and that the bundle stops after 1.5 seconds at a height 's' with a final velocity 'u' -which would be 0.

Our known values thus are:

Time (t) = 1.5 s

Final velocity (u) = 0 m/s

Gravitational acceleration (g) = -9.8 m/s^(2)

Note: that the acceleration is negative as it is opposing the direction of motion (acting  down on the object, causing deceleration)

We will be using equations of motion for an accelerating object to solve first for initial velocity, in order to find the distance.

Rearranging the equation, and using the value 'g' as our acceleration, we get, u = v - at

u = 0 - (-9.8)(1.5) = 14.7m/s

Rearranging the equation, we get, s= v^(2) - u^(2) / 2a

s = 0^(2) - 14^(2) / 2(-9.8)                          

Note: the negative sign is not a part of the initial velocity, but a part of the equation

s = - 216.09 / -19.6 = 11.025 m

The distance traveled by the bundle is hence, ~ 11 meters, which is high enough for the girl to catch.

Hope this helps!

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
