A particle starts out from the origin with velocity 10ms^-1 and continues moving at the velocity for 5s. The velocity is then abruptly reversed to -5ms^-1 and the object moves at the velocity for 10s. For this motion find a. The change in position, i. e. displacement
B. the total distance travelled
C. Average speed
D. Average velocity

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.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
