Atoy rocket moving vertically upward passes by a 2.0-m-high window whose sill is 8.0 m above the ground. the rocket takes 0.15 s to travel the 2.0 m height of the window. what was the launch speed of the rocket, and how high will it go? assume the propellant is burned very quickly at blastoff.

Explanation:

As we know that the speed of the rocket is v1 and v2 at the bottom and top of the window

then we will have

also we know that

now we have

also we have

now if the sill of the window is at height 8 m from the ground then we have

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
