A block of mass 1.58 kg which is initially at rest is acted upon by an impulse of 8.22 Ns due to a constant force. The impulse lasts for 0.187 s seconds and results in the mass moving at velocity v. The block then slides up a frictional ramp which has a length 2.00 m and a height 34.8 cm before colliding with a mass 3.16 kg . In this problem all horizontal surfaces are frictionless (only the incline is frictional). A) With what velocity does the mass move after the impulse acts upon it? v = m/s
B) What average force acts upon the mass during the impulse? Favg = N
C) If the block reaches the top of the incline with velocity 3.91 m/s , what is the coefficient of kinetic friction of the ramp? μκ =
D) If the 1.58 kg block collides and sticks to the 3.16 kg block, what final velocity results? Vfinal = m/s
E) How much Kinetic Energy was lost in the collision of the two blocks? KElost = ___ J

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

amplitude

hope this
